This section chronologically documents the
changes (enhancements and bug fixes) that have been made to uCon. The
changes documented here begin with uCon as of Nov 1, 2003. Note that
this is obviously not an official change log, rather a page that allows
users to be informally kept aware of improvements made to the tool.
Having stated that, please report all bugs and or enhancement requests
to Ed Sutter.
Aug 8, 2022 (SVN=1438):
Formats to the -f option of the TIME commmand now accept :msec appended.
May 12, 2022 (SVN=1435):
Fixed a bug that would cause uCon to hang if the COM port failed.
Apr 25, 2022 (SVN=1431):
Added a new 'port#' alterantive to the CONNECT script command. Refer to that page for details
Changed algorithm when creating the COMPORTS drop-down list so that actual COM ports are listed at the top.
Mar 14, 2022 (SVN=1427):
Added a few new baudrates to the comport dialog box used at startup.
Oct 18, 2021 (SVN=1423):
More cleanup of XMODEM script command's setting of SCR_TIMEOUT and XmodemState.
Oct 12, 2021 (SVN=1421):
New -r option to XMODEM to change retry count. Refer to XMODEM script command for more info.
Apr 2, 2021 (SVN=1418):
CONFIG color supports background-save and background-restore. Refer to CONFIG script command for more info.
Mar 30, 2021 (SVN=1417):
Bug fix: The XMODEM script command was not properly setting the SCR_TIMEOUT shell variable when -t option is used.
Specifiying -n and -t on the XMODEM command is contradictory, so that is now flagged as an error.
XMODEM command will populate the XSTATE shell variable to indicate pass (IDLE) or fail (FAIL).
XMODEM during a script will not generate a dialog if there is an error, the error will simply be printed to the console.
Feb 8, 2021 (SVN=1415):
you start uCon with the Telnet backend the shell variable
TELNETBACKEND_IP will be populated with the IP address of the server,
and TELNETBACKEND_PORT will be populated with the port used.
Similarly, if you start uCon with the putty (SSH) backend, the
shell variable .PLINKBACKEND_ARGS will be populated with the "Plink Args" as specified on the opening dialog.
Oct 6, 2020 (SVN=1414):
The uninstaller recently
caused some trouble, so I am removing it from the installation.
When time allows I will try to understand what caused the
trouble. For now, if you need to remove uCon, just delete the installation directory manually.
May 27, 2020 (SVN=1408):
The ucon_install.exe installer no longer defaults to a C:\program files (x86)\ucon installation directory.
This has always been changeable by the user at the time of install, but with the last few versions of
Windows, C:\program files (x86) has become a bit less friendly. As a result, it is now up to the user
to specify the directory. The recommended place is $DOCUMENTS\ucon.
May 26, 2020 (SVN=1406):
New 'strstr' sub-command to the STRING script command.
New 'timestamp' sub-command to the CONFIG script command to enable or disable timestamping.
Bug fix: The FILE "first/next" sub-commands had two problems:
1. 'next' erroneously required an argument
2. The first file was omitted.
Both issues are fixed.
Mar 4, 2020 (SVN=1402):
Added support for COM port numbers up to 1023 (yea, apparently you can have a very high COM port number, I did not know that...)
Jun 24, 2019 (SVN=1396):
Bug fix: When the CONNECT command was used to establish a TELNET
backend, it was possible for the command to return before the newly
spawned thread actually established the connection. This is
fixed, the CONNECT command will now wait for the connection to be
established (or fail).
- Bug fix: The SLEEP command did not deal with values greater than 0x7fff on 32-bit windows machines. This is fixed.
- New read-only variable: UCON_BACKEND will contain the current backend (NONE, COMPORT, TELNET, MONCMD, PLINK).
New feature: if SHOW_LASTERROR_TO_CONSOLE is set, then error messages
that would normally use the blocking dialog box will print to the
console and continue.
Jun 10, 2019 (SVN=1388):
- When an attempt was made to execute a script (through a button or function key) while another script was already active, the new attempt would be rejected. If the system trace window
was active and SCRIPTS trace was enabled, the the user would see the
warning message which indicated that the attempt to run a second script
while another script was running was denied. To make this a bit
more obvious, I added a dialog box that will notify the user and ask if
they want to halt the currently running script to allow the new one to
Jan 29, 2019 (SVN=1383):
- New timestamp format: yyyymmdd-hh:mm:ss.msec.
Oct 1, 2018 (SVN=1364):
- Bug fix: The SEND script command was no properly dealing with \x00 if it was part of the string to be sent; now it does.
Aug 28, 2018 (SVN=1355):
- Bug fix: The SEND script command was no properly dealing with \x00 if it was part of the string to be sent; now it does.
Jun 18, 2018 (SVN=1352):
- Bug fix: As a result of a change I made to support the outgoing ACH feature, I inserted a bug related to the 'DBC' (delay-between-characters)
feature with strings of text that are programmed into function keys
and/or buttons, In the nutshell, the delay-between-characters
setting was ignored for buttons and function keys. This is fixed.
- Bug fix: The WOL command's -v (verbosity) option was not working. Fixed now.
As part of the above fix, I also cleaned up the way long strings of
characters are sent to the target. Any long string really needs
to be pushed to the target in its own thread; otherwise the main window
is held up waiting for that string to be sent. This is only
noticed when the combination of string length and/or dbc setting
results in a transmission time that is noticeable (a few seconds or
more). The main window will lock up and the user won't see the
string until it is entirely pushed to the target. Now, with this
in a thread, the user will see each character as it is sent and the
window will not be locked. This is primarily a cosmetic
Jun 7, 2018:
Bug fix: Changing COM port connections during an open session of uCon
caused some confusion; in some cases this caused the user to have to
open the port twice (because on the first attempt it remained
disconnected); and in the case of a user-defined baud-rate, this would
cause an endless loop essentially killing the uCon process. This
May 17, 2018:
When there is a disconnect from the comport, if keepalive is active,
uCon will prompt the user as to whether or not it should be shut
- Bug fix: the RTSSET and DTRSET checkboxes weren't properly
pre-configuring RTS and DSR pins; they were simply disabling the
appropriate flow control if the box was checked. As of this fix,
if RTSSET is checked it will correctly disable RTS/DTS flow control,
but it will also enable RTS pin at startup. Similarly, if DTRSET
is checked, it will disable DTR/DSR flowcontrol, but it will also
enable DTR at startup.
- The keepalive feature added to the CONFIG command will only run if the backend com port is connected.
Apr 17, 2018:
- New keepalive option...The CONFIG
command has a new 'keepalive' subcommand which allows the user to set
up a script that will automatically run periodically based on the
Apr 16, 2018:
- New inactivity timeout option...The CONFIG command has a new 'inactivity'
subcommand which allows the user to establish the inactivity timeout as
well as an optional script to run in place of the actual disconnect.
Mar 19, 2018:
- New options for the SLEEP script command to support sleeping till mouse click or keystroke.
Mar 12, 2018:
More work on the new Transfer->Text menu item...
Mar 8, 2018:
New Transfer->Text menu item... will open a small dialog box
that allows the user to pre-type the string into the text box and the
- Bug fix: the "Send-on-Enter" mode was ignoring "Local Echo".
Feb 7, 2018:
- New script command SENDINPUT. Allows uCon the ability to simulate keyboard intput to other applications..
Feb 6, 2018:
- New RESTful interface in HTTP server for issuing script commands, or button/functionkey pushes.
Jan 2, 2018:
- The startup dialog box now allows you to enter a user-defined baudrate.
- If uCon is running with a user-defined baud rate, then the"next baudrate" toolbar button is used as a 1-click means of opening the Config->Backend->ComPort dialog.
Dec 14, 2017:
- New "alternate com port" option that provides monitoring of a second COM port.
- New "send-on-enter" character entry option... characters are accumulated until -ENTER-
Nov 6, 2017:
- Fixed bug in the ANY option of comport selection... It wasn't dealing with comport numbers greater than 9.
- New AVRLOADER script command for downloading arduino sketches to optiboot-based boards.
Mar 16, 2017:
Updated the version of plink, based on putty-0.68.
Feb 1, 2017:
For systems that have
more than one IP address, there's a chance that the MYIP shell variable
will not be set to what you expect. There's really no way (that
I'm aware of) to pick a particular IP address within your list of
network interfaces, uCon just assigns the first one it sees. To
allow the user to configure a particular uCon session to a particular
IP address (and affect the status bar and the MYIP setting), you can
now export the MYIP shell variable and save your config so that next
startup that IP address will be loaded into MYIP and the status bar.
Also, as part of this, I added a new CONFIG subcommand: "nicinfo", to list the known IP addresses (1 per NIC).
Jan 13, 2017:
Ymodem is implemented. Because of the limited number of systems
to test this on, its tough to be sure if its fully operational.
It appears (based on user feedback) that it does not handle error
recovery; however if no errors occur, the transfer (using u-boot as the
target) works ok.
Added MODBUS crc (big & little endian) to the set of ASCII-Coded Hex (ACH) mode checksums. Refer to Miscellaneous Config Items dialog.
Strings sent through function keys and/or buttons now pass through ACH processing.
Jun 20, 2016:
New ACH option to local-echo. Refer to Miscellaneous Config Items dialog.
May 4, 2016:
New argument for RECV blkcpy
script command. If a filename is specified, then the content of
the received buffer will be written to it (instead of RECVBLOCK shell
variable). This is useful because at times, the size/length of
the RECVBLOCK variable is too large to deal with as a shell variable.
New -n option used with RECV blkinit to turn off automatic wrapping (circular queue) of the incoming data.
Apr 15, 2016:
New sub-command for FILE script command: dump. Simply dumps the content of the file to the console.
New options for the LOG script command. Supports the dialog box options available through Logging->Standard menu item.
Feb 3, 2016:
New sub-command for the LOG script command: trunc. Just gives you the ability to truncate the currently active logging file.
Jan 15, 2016:
New sub-command for the FILE script command: hexdump. Just gives you the ability to dump a file (or a portion of it) in ascii-coded-hex format to the console.
Nov 3, 2015:
script command "SRVRSETUP", added to support server configuration from
a script. As of now, all this does is allows the user to turn the
dhcp server on and off; as needs arise, I'll update this capability.
Sep 15, 2015:
code in RECV that waits for a string had a bug: If a portion of the
string is received, then the actual string is received after some valid
substring, the state machine was failing. For example, if the the
command was RECV -x 11223344, and the incoming data was 112211223344,
this would be missed because the restart was within a valid substring
of the match.
Aug 14, 2015:
To support overriding the default SSH port number, the plink argument list can now be appended with the familar port syntax using ":PORT".
Aug 13, 2015:
New 'restore' and 'minimize' sub-commands to CONFIG script command.
Aug 12, 2015:
Back in June I "fixed" something that caused some problems with some folks...
I realized that FileBrowser that comes with the Microsoft environment
(used by uCon) will, by default, change the current working directory
(CWD) to whatever the directory of the selected file is. That's
not what I wanted it to do, so I changed it so that the CWD is not
affected by any file opened with the browser. Unfortunately, this
also causes scripts that are invoked from Scripts->Run (using the
browser) to not automatically change the CWD to the directory from
which the script is invoked. This is bad for any script that uses
relative file paths and assumes the CWD was changed.
So, I added an
exception so that launching a script from Run->Scripts (using the
browser) will still do the change-directory, but in all other cases the
CWD is left untouched when using the browser.
Jun 11, 2015:
Buttons and function keys can now be colored using their configuration dialogs or the 'FKEY' script command.
Jun 10, 2015:
If uCon starts up with a config file, and there is no specified "Titlebar" text in the Miscellaneous Configuration, the title bar text will include the name of the config file.
May 18, 2015:
Made some improvements to cut-n-paste.
May 7, 2015:
Added line-tagging option to the CATCH
facility. This gives the user the ability to have uCon append a
line tag at the far-right edge of the console window on every line that
contains a catch string.
Apr 22, 2015:
You can now open up a CMD shell to run within the uCon console... Why would you want to do that?.
New -C option for RECV script command.
Apr 13, 2015:
Similar to the LINES variable, now each time the window is resized, the COLS variable is loaded with the width.
Mar 27, 2015:
Standard logging now supports logging non-printables.
Mar 12, 2015:
New 'CRC32/MD5' dialog.
Mar 11, 2015:
New 'md5' sub-command added to the script command FILE.
Mar 10, 2015:
fix: Config->Backend was not properly opening the port if uCon started up with a preconfigured port that was invalid.
Bug fix: The toolbar buttons related to RS232 control were not disabled when the port was disconnected (they are now).
Bug fix: If there is an error in the config file at startup, uCon now allows the user to ignore the error and continue.
Feb 5, 2015:
fix: if you move the window around (or even just left-click in the
outer edges of the window) uCon would drop the characters received
during that period if VT100 emulation was enabled. This is fixed.
Jan 30, 2015:
The timestamp facility now allows you to specify a custom format.
Jan 16, 2015:
New 'crc' sub-command added to the script command FILE.
Jan 9, 2015:
Set up very low-traffic mail list subscription: http://www.umonfw.com/ucon/joinlist.html
. This is not a "forum" style list, just a list that I will use
to send out notifications to users (bugs, bug fixes, new features,
Dec 15, 2014:
Disallow uCon from starting up with a window height that exceeds the size of the PC screen.
Dec 2, 2014:
If the comport is via USB, and the USB connection drops or hangs for some reason, uCon will now automatically disconnect.
After that type of automatic disconnect, uCon will attempt to reconnect each time a character is typed into the console window.
Oct 14, 2014:
installer now does something different if /S (silent mode) is detected.
Until now, the installer always asked the user for permission to
overwrite an existing installation of uCon, and it asked if the user
wanted to install a desktop shortcut. Now, if the /S option is
provided on the command line (i.e. ucon_install.exe /S), then an
existing installation will automatically be overwritten and a desktop
shortcut icon will be automatically installed; both without user query.
This allows folks to use /S and /D (specify the installation
directory) as command line options to the installer so that it installs
quietly. See the "uCon Installation & Removal" page for more information.
Oct 10, 2014:
The function keys and buttons now support right-click access to either the script they have loaded or the dialog box used to set the command.
Sep 19, 2014:
The function keys and buttons will now show tooltips with the execution string or script.
Sep 9, 2014:
The console window can be put into -readonly- mode.
Sep 4, 2014:
Bug fix: ClearScreen() was not properly dealing with a vertically scrolled window.
Feature: User can now change the console font.
Improvement: More robust handling of remote end timeouts in XMODEM.
Aug 27, 2014:
Bug fix: xmodem receive was not properly dealing with packet retransmissions (fixed).
Bug fix: if uCon was opened with a NULL or LPBK port, you could not reconfigure to a normal connection (fixed).
Improvement: port scan is faster.
Aug 20, 2014:
Bug fix: the standard logging 'Truncate' action could cause a crash under certain circumstances (fixed).
Feature: new sub commands to CLS script command to support changing text attributes applied only to new incoming data.
Feature: the size of the buffer used to store incoming characters when the screen is scrolled off home is now configurable (see Config->Miscellaneous).
Feature: the header written to the log file now includes time/date.
Aug 8, 2014:
The 'blkinit' function within the RECV script command now allows you to specify the size of the block.
uCon's scripting engine now supports Lua.
Aug 6, 2014:
uCon now supports floating point operations on variables. Refer to the -f option of the SET and IF commands for more information .
July 17, 2014:
uCon now supports remote console through HTTP. For more information on this, refer to the HTTP server page.
July 8, 2014:
New SOCKET script command, allows user to interact with other UDP/TCP servers.
June 13, 2014:
New option to the EXIT command: ALLSCRIPTS will terminate all running scripts.
June 9, 2014:
The LOG append script command will create the file if it doesn't already exist (instead of terminating with error).
New -h option for CATCH script command.
May 28, 2014:
'any-char' token (a dot) and 'anything-till-eol" ("*\n") string can now
be used when specifying a "catch string" in the CATCH script command
May 20, 2014:
Added new 'line' sub-command to the script command FILE.
May 5, 2014:
New WOL (wake-on-lan) command.
Apr 30, 2014:
The port used by the telnet server is now configurable.
Apr 24, 2014:
telnet client backend has the ability to automatically restart the
connection (AutoRestart) if the server dies. In addition to that,
if the user has specified a startup script, and the shell variable
'RUN_STARTSCRIPT_ON_RESTART' is set to TRUE, then the startup script
will rerun when the connection is re-established. When using the telnet
client as the backend, if AutoRestart is enabled and and the connection
Mar 31, 2014:
script command has a new -c option and also supports using '.' as an
incoming character (meaning any character will be accepted).
Jan 16, 2014:
now, if characters were incoming when the console window was scrolled
vertically, those incoming characters would force the vertical scroll
position back to zero so that the incoming characters would be seen.
This is now changed so that incoming characters will be buffered (up to 32K) until the scroll position is restored or a character is manually typed in by the user..
Jan 14, 2014:
Added new 'appendf' sub-command to the script command FILE.
Jan 6, 2014:
Fixed a bug in the TIME script command related to the -f 'j' option..
Oct 19, 2013:
The TFTP client script command now populates TFTPC_ERRNO and TFTPC_ERRMSG with the transaction's error number and error message (if an error occurs).
Oct 11, 2013:
"special" shell variables: THISSCRIPTDIR & THISSCRIPTNAME.
Each of these variables can be accessed by a running script.
In particular, THISSCRIPTDIR is useful for cases where scripts
use files that are located relative to the location of the script..
Oct 10, 2013:
New -t option to ECHO script command to put text to system trace window.
Oct 9, 2013:
New menu item 'File->New' allows the user to open a new uCon session.
Multi-line copy-n-paste is now working.
Oct 8, 2013:
New configurable item 'RtBtnIsPaste' which, when set, will tell uCon to use the right mouse button as a 'Paste" command.
July 22, 2013:
New '-a' optino for CATCH script command.
June 24, 2013:
New 'token' subcommand for use with STRING script command.
May 30, 2013:
a session starts with the COMPORT connection set to NONE, subsequent
configuration saves will not include a changed backend setting.
This allows a user to set up a backend-agnostic configuration
file; so that the same configuration can be used on various backend
connections by simply making that connection after the session has been
started and pre-configured.
May 16, 2013:
New script command: EVENT
This allows multiple uCon sessions to use events to synchronize between sessions.
May 15, 2013:
- Bug fix 1: fixed an issue that may have been causing stability issues with some USB-to-Serial dongles.
- Bug fix 2: only noticed if running multiple uCon sessions each of which have running scripts.
May 9, 2013:
Added a -D option to the uCon command line so that a shell variable can be specified at startup: -D Var=Val
is useful if multiple uCon sessions are started and are to use one
script, now each session can have a unique variable that can be used in
the script to distinguish between the sessions and invoke different
May 6, 2013:
Added support for display/monitoring of incoming modem
control lines and a 'break' signal. The user can see the state of
DSR, DCD, RI and CTS by observing new buttons on the toolbar. These state changes can become "inline" if enabled with the new "inline-signaling" checkbox in Config->Miscellaneous.
Apr 29, 2013:
The buttons can now be used to invoke a single-line script command.
Apr 24, 2013:
New menu item under logging that allows user to disable the automatically inserted message into the log file each time it starts up.
Apr 2, 2013:
Fixed an issue that could have caused the 'CATCH' facility not to work when set up through the GUI.
Mar 27, 2013:
Increased MAXCOMPORTS (internal #define) from 64 to 128 to support *really* high comport numbers.
Mar 22, 2013:
New 'FKEY:' and 'BUTTON:' command for MONCMD server.
Fixed a bug that caused uCon to crash in some cases if the baudrate was incorrect during a disconnect.
Mar 11, 2013:
New 'color' sub-command to the CONFIG script command. Allows the user to secify the color of text, alternate-text and background..
Mar 8, 2013:
Added the 'what' subcommand to the FILE script command to support the ability to extract "what strings" from files.
Mar 7, 2013:
Fixed a bug that was causing RTS/CTS flow control to be disabled erroneously.
Mar 4, 2013:
- New -r option to DIALOG script command, allows the user to override the default use of the DIALOG shell variable for storage of the result.
- New -h option to SET script command, allows a variable to be hidden from view when the environment is dumped to the console.
- New PQ_AND_A command option for the DIALOG script command. Adds some privacy to the user input.
- Over the last few weeks, I've been cleaning up the
cut-n-paste capabilitiy in uCon. There's no longer any need to
enable "character attributes" and while it still isn't working for
multi-line swipes, single line is in pretty good shape for both swiping
text and double-clicking to quickly capture a whitespace delimited
Feb 22, 2013:
New 'httpget' sub-command to the FILE script command (this is a work-in-progres, currently it does not work with a proxy).
The 'token' sub-command to the FILE
script command now allows you to specify a delimiter (instead of only
defaulting to whitespace). I've tested this with Excel generating
'csv' output files (comma delimited) and it works pretty well.
Feb 22, 2013:
Text and background colors are now specified with a 'colors' dialog box instead of just using raw RGB values.
Cleaned up some nagging issues that should make single-line cut-n-paste work a bit better.
Feb 20, 2013:
When "Echo outgoing characters to screen" is enabled, the user now has the option to specify the color of those characters.
Feb 7, 2013:
New 'bringtofront' sub-command to the CONFIG script command. Simply brings the window to the front-most position.
New 'copy' , 'move', 'd2u' and 'u2d' sub-commands to the FILE script command.
Dec 14, 2012:
New 'mkdir & rmdir' sub-commands to the FILE script command.
Dec 7, 2012:
New 'trace' sub-command to the CONFIG script command. Allows a script to enable/disable script tracing.
Dec 5, 2012:
New 'BACKUP' script command, provides SCRIPT based access to the menu item uMon->Backup uMonFS.
Dec 1, 2012:
New 'contains' test in IF script command.
Nov 14, 2012:
Fixed a screen refresh bug: if uCon was minimized by
WINDOW-D, then re-normalized portions of the window did not properly
update. Should be better now.
Oct 18, 2012:
The HiRes timer item in the Config->Miscellaneous dialog box is no longer saved to the config file.
a bug in the command line processing of the config file so that ther
user only needs to specify the path of the file relative to
Sep 25, 2012:
Added -b (banner) option to ECHO script command.
Sep 21, 2012:
Added CONTINUE action to the IF script command.
Sep 18, 2012:
HTML-based documentation is now part of the
installation; allowing systems to retrieve HELP even if not tied to the
Internet. There is also one new help item that points to the
Sep 14, 2012:
- Added new conditional tests to IF script command: ismac (MAC syntax checker) isip (IP syntax checker), ishex (hexadecimal checker) and isdec (decimal checker).
Added a new intrinsic shell variable SVNREV, which will always contain
the SVN release number for which the running version of uCon was built
from. This is useful for scripts that incorporate new features
and need to make sure that they are being run by a version of uCon that
supports those features. For example, if I add a feature into
revision 987 that you need, then you would just add a check in your
script (example: IF $SVNREV lt 987 GOTO UPDATE_UCON) to make sure the environment is up to date.
- Added RECVBLKTOT shell variable to the RECV script command.
Sep 10, 2012:
Added new SHELLEXEC script command, as a wrapper to the ShellExecute API call discussed in MSDN.
Aug 10, 2012:
New 'Inverted Mod100' added to the list of checksum/crc methods available to the system.
Jul 25, 2012:
New CONFIG command to support (eventually) all operations that can be clicked through in the Config->Miscellaneous dialog box.
New options to the ECHO command to support the ability to more conveniently print delimited ascii coded hex.
Jul 23, 2012:
Added a new timestamp, that provides millisecond resolution. Note that this is only as accurate as the Win32 SYSTEMTIME structure supports.
Jul 9, 2012:
New 'Fletcher' CRC16 added to the list of checksum/crc methods available to the system.
Jul 7, 2012:
The STRING command now supports all of the checksum/crc methods as listed in the Config->Miscellaneous dialog box.
Jul 5, 2012:
script command: the data recevied will be loaded into the RECVBLOCK
shell variable when using new 'blkinit' and 'blkcopy' subcommands. The new -a option tells RECV to do a
binary-to-ASCII-coded-hex conversion prior to populating RECVBLOCK.
New -C option available to SEND
script command allows the user to specify the same checksum/crc
algorithm to be applied when using SEND -x for transferring
ASCII-coded-hex. Also, added new checksum (CRC16) type for use
with ASCII-coded-hex data transfer.
Jul 2, 2012:
Bug fix: Under the Config->Backend->Comport dialog
box, if the user changed the port and also had set a custom baud rate;
it would not work. The custom baud rate change was being applied
prior to updating the port; hence, it was never being successfully
applied to the desired port. Note that this only shows itself as
a problem if the port is changed at the same time.
Jun 26, 2012:
Added the ability to put the uCon console into an
ASCII-coded-hex convert mode so that all characters typed on the
console are assumed to be ascii-coded hex. When <ENTER> is
received, the block of data is converted and sent. Optionally a
checksum can be applied. Refer to the Config->Miscellaneous dialog box for more information..
Jun 25, 2012:
Added the ability to insert a space between each
character when ASCII-Coded-Hex-Conversion of incoming characters
(Config->Miscellaneous) is active.
vt100 emulation of colored text and background. This requires
that the "Enable-Character-Attributes" mode (Config->Miscellaneous)
be enabled as well.
Jun 22, 2012:
Added a new script command called AUXCOM.
Primarily intended for use with ARDUINO boards to add additional
coordination between the backend connection and anything you want to
connect to with an ARDUINO.
Jun 21, 2012:
The -p option to the SEND command now accepts "\x" so that you can specify non-printables in the prompt.
Jun 20, 2012:
Added a new SRVRSETUP sub-command to TFTP script command to allow the user to turn on/off the TFTP server from a script.
Jun 18, 2012:
Added a new DBC sub-command to the COMPORT script command to allow the user to redefine the delay-between-characters value from a script.
Jun 12, 2012:
The textbox in the Transfer->Binary ("Transfer ASCII
Coded Hex as Binary") dialog now supports automatic horizontal
Fixed a bug in RECV -x command: it did not work if
uCon was configured to display incoming binary as ascii-coded-hex.
Now it does.
Feb 23, 2012:
Fixed a few screen-paint/refresh issues reported by a user.
Jan 26, 2012:
Added a 'tag' subcommand to the scripting LOG command. See the LOG script command for details.
Jan 21, 2012:
The port scan output shown in the initial uCon dialog
box now only shows COM ports that are configured in the registry.
No more "not-in-registry" ports displayed in this dropdown.
It also starts off by displaying the currently active port (if
Dec 20, 2011:
The TFTP server in uCon is now multithreaded to support multiple simultaneous TFTP transactions simultaneously.
Nov 22, 2011:
The state of DTR and RTS are now saved in config.
Also, the COMPORT command now has additional arguments: DTRSET, DTRCLR,
RTSSET & RTSCLR.
Nov 1, 2011:
The Telnet server supports a new mode that allows the
first connection to be read/write and all subsequent connections
Sept 26, 2011:
The TFTP server now supports multiple simultaneous file transfers.
May 13, 2011:
Added the ability to establish a loopback COM port.
When connected to this "dummy" comport, all that is pushed to the
port is echoed back..
Mar 16, 2011:
Bug fix: the F2/F3/F4 keys were attempting to send characters (if pressed) to the COM port even if the port was not opened.
This action is now filtered by the state of the COM port.
Feb 24, 2011:
New feature: to turn off the console output of data from the target, LOG screenon and LOG screenoff are now available.
Feb 16, 2011:
Bug fix: Automatic execution of startup script should not be done till after the COM port is opened.
Feature: Added the ability to disable the config file diff check.
Bug fix: The lastScriptName is excluded from the config-diff.
Dec 23, 2010:
Bug fix: There was a case that uCon could get
in that would cause it to enter an empty loop; thus, hogging the
CPU. At least one of these cases has been fixed.
Nov 24, 2009:
Bug fix: a buffer overflow bug was causing some folks to crash on uCon startup. This issue has been resolved.
The installer will now push the current version of uCon
executables to the 'bak' directory prior to doing the installation.
This allows for a 'quick' recovery if for some reason the new
installation is broke.
Sept 1, 2009:
When a log file is created, it is now stamped with the version of uCon (SVNREL) that created it.
Aug 1, 2009:
Two new shell variables are populated at startup: MYNETMASK & MYGATEWAYIP.
July 16, 2009:
New "-s" option in XMODEM script command.
New "-V" option in FILE script command.
July 12, 2009:
Added a new option (-d ##) to the SEND script command. This allows SEND to specify the delay-between-characters setting for just the output of that command's data to the target.
July 11, 2009:
The "command" text that can be specified when using
XMODEM is now forced to have a 50-millisecond delay between characters
regardless of the current DBC setting.
June 9, 2009:
More regarding the DTR/RTS changes made on Jun 8: the
buttons on the toolbar will reflect the state of the signal. If the
button is depressed, then the signal is active; if not depressed, the
signal is inactive. Also, the COMPORT script command now has a RTSTGL command (similar to the DTRTGL command already there).
June 8, 2009:
As an extension to the changes of June 3, uCon now comes
up and initially populates the ComPort combobox with data retrieved
from the registry rather than from state gathered by opening/closing
the port. Additional information can be gathered with the "PortScan"
button to see which (if any) available ports are actually in use.
Some additional cleanup of how DTR and RTS are initially set up has been done.
The "toggle DTR" function on the toolbar used to just
provide a momentary change of state to the DTR pin. If it was high,
then this button would bring it low for one second, then return it to
the high state. If it was low, then this button would bring it high for
one second, then back low. This functionality is changed so that now
the button simply inverts the state and leaves it that way; thus,
allowing the user to toggle by simply clicking the button twice.
Added a new "toggle RTS" button on the toolbar. It does
exactly the same thing as the "toggle DTR" button, except that it
applies to the RTS pin of the RS232 port instead.
June 3, 2009:
When uCon started up, it would attempt to open all
possible comports (up to COM32), and if the open succeeded, it would
close the port, but then tag that port as available for use. This
provided a convenient means of seeing which ports were available on the
machine; however, it also caused each available port to be "glitched"
by the quick open/close call set. The "glitch" would show itself as a
momentary change in DTR and/or RTS lines on the port itself. In some
cases, this glitch can have a negative affect on equipment that may be
attached to the port. So, now uCon comes up without that scan, but the
user can just click a button on opening dialog to generate the scan.
May 28, 2009:
Added the ability to establish the initial state of the
DTR and/or RTS bit when the corresponding flow control bit is not set.
So, if DTRDSR flow control is not enabled, then DTR can be set or
cleared at startup. Similarly, if RTSCTS flow control is not enabled,
then the RTS bit can be set or cleared at startup.
May 26, 2009:
The BMPVIEW script command now supports RGB mode (see BMPVIEW command for more info).
May 7, 2009:
Fixed a few problems in the DIALOG command
noticed only when only one of the dimension options (w & h) was
specified. The code was erroneously setting the 'other' dimension.
Fixed a bug in the script runner's command line parsing
that was causing some unusual cases of backslashes and dollar signs not
Mar 13, 2009:
Fixed a bug in handling daylight savings time, update to 7.1.
Mar 2, 2009:
The text argument used by the DIALOG script command now
properly parses "\n" so that newlines can be inserted into the text
placed in the dialog box. Also, for cases where a lot of text is to be
put in the dialog box, the shell variables DIALOG_LX (where 1 <= X
<= 100) can be loaded with text that will be concatenated onto the
Feb 25, 2009:
Fixed and cleaned up the MONCMD backend stuff.
Added the ability to set a different port number in the SYSLOG server.
Oct 22, 2008:
Fixed a bug in the script execution engine that was only
noticed if the SEND command was running and more than 512 characters
were received without any of them being a carriage return and/or line
feed. The code that keeps track of the last line received had a buffer
overrun bug (now fixed). Also, in the process of searching for this
bug, I optimized two other snippets of code that should make uCon a bit
more CPU friendly under certain circumstances.
Update to 6.9
Oct 3, 2008:
Fixed a bug in the FSEND
command that is only noticed when large (i.e. >= 500K) files are
transferred, and data is being received on the same COM port while data
is being sent.
Sept 1, 2008:
New item under the Scripts menu... You can now set up
your buttons and function keys, then store away that configuration to a
script that can be run later to establish that same function-key/button
setup. Refer to the Script menu item page for more information.
July 18, 2008:
The function keys/buttons now support '\xHH' syntax for
entering ASCII-coded-hex values for individual characters. Refer to the
function key/button help page for more information.
Jun 9, 2008:
Bug fix: in the Logging->Standard dialog box, if the
"append" checkbox is checked, and the file doesn't exist, uCon would
complain that the file didn't exist. This is changed so that if no file
exists, it will create one. Then, the normal situation (when a file
exists) will work the same way.
May 22, 2008:
Update to 6.8
New script command: catch.
This command allows the user to tell uCon to wait for a specified
string from the target, and when that string is received, run a
specified script. Note, this is done in the background while an
otherwise normal uCon session is running. Refer to the CATCH script command page for more information.
May 21, 2008:
New script command: STRING. This command allows the user to do some parsing on a specified string.
Apr 5, 2008:
The TFTP server in now supports the blksize option
request. Prior to this, the server not only didn't support the blksize
request, but if the request came in, the server would hang.
Mar 24, 2008:
Bug fix: The items in the group box "ASCII-coded hex conversion of incoming characters" of dialog Config->Miscellaneous were not properly saved to configuration file. This is now fixed.
Mar 11, 2008:
Added the ability to disable uCon's use of the Ctrl-V key as a 'paste'. Refer to the Config->Miscellaneous dialog box for more information.
Feb 15, 2008:
Added a new item to the floating pull-down menu, which
is available when you right-click while in the console window... Along
with the ability to open up an editor on the entire screen buffer (i.e.
"Edit Screen Buffer"), now you can open up an editor on only the text
in the viewable screen: "Edit Screen Only".
Jan 30, 2008:
New '-t' option to the TITLE script command. Allows a
script to change the Welcome message that is presented to the telnet
client when it connects to uCon's backend telnet server. Refer to the TITLE command for more info.
Added two new remote commands: fkey, button & scrcmd. Refer to the remote command help text for more information.
Dec 7, 2007:
Added two new capabilities to the 'strstr' sub
command of the script command FILE... If the string is found, populate
the shell variable 'LINE' with the line at which it was found. Also, if
an additional argument is specified (see the FILE 'strstr' sub-command for more details), then require that the 'N'th occurance be found, not the first.
New FKEY command capability: any button or function key can be enabled or disabled via script. Refer to FKEY command for more information.
Dec 3, 2007:
If the configuration has changed, and the user attempts
to exit without saving it, uCon will now post a warning and give the
user the opportunity to save the changed configuration.
TFTP server port number (default=69) can be overridden if the TFTPSRVR_PORT shell variable is set in uCon's environment. See TFTP server for more details.
TFTP client port number (default=69) can be overriden if the server ip address is followed by a colon and an number. See TFTP client for more details.
New "NoBeep" checkbox in Config->Miscellaneous menu item. If checked, then the "bell" character (0x07) will be muted.
New "-c" option to FKEY script command. This allows the
user to keep track of the number of times a button or function key is
hit. Refer to FKEY script command for more information.
New "-t" option to DIALOG command to allow the user to specify the text in the title bar of the dialog box created.
Nov 16, 2007:
Two new subcommands to the FILE script command: first
& next. This allows a script to walk through filenames in a
directory. Refer to the FILE command for more information.
Nov 15, 2007:
The DIALOG command now allows the user to override the default dimensions of the dialog box created within the script.
Nov 9, 2007:
New script command: BEEP Refer to command help text for details.
New option to CONNECT command: 'close'. Simply closes whatever connection was previously opened.
Oct 31, 2007:
Added the ability to change the font and console
backround colors through a script. This is done with sub-commands built
into the CLS command. Refer to that command for more information.
Oct 11, 2007:
The timestamp facility in uCon now allows you to insert a timestamp whenever the timestamp button is toggled. Refer to the timestamp page for more information.
Oct 3, 2007:
The FKEY script command
now allows you to omit the "label" and "text" arguments, to indicate
that the specified button or function key is to simply be cleared.
Sept 27, 2007:
New "copyscreen" subcommand to FILE script command to give a script the ability to copy the content of the screen buffer to a file.
Bug fix: Fix #2 from Sept 20, uncovered a
problem with screen resizing, that until now has gone
unnoticed/unreported... If the screen width is decreased (to a point
where characters on the console are chopped off), then re-increased,
the chopped off characters are lost. This is no longer a problem.
As a result of the Sept 20, 2007 fixes, a
few other coding issues surfaced. The result is that I re-wrote the way
that uCon deals with screen-width resizing. The change was reasonably
significant (i.e. it can affect a lot of different parts of the GUI),
so hopefully I've covered all the areas of concern. If any weird stuff
happens during screen-width resizing, please report them.
Sept 20, 2007:
Bug fix 1: problem with timestamping (where some lines would not be time stamped) is fixed.
Bug fix 2: crash that would occur as a result of resizing the window (intermittent) is fixed.
Sept 11, 2007:
Added the ability to change the color of text and background in the console window. The settings are in the Config->Miscellaneous dialog box.
Aug 22, 2007:
Updated to release 6.7.
This is the first pass at testing uCon with Wine.
I personally do not have a recent enough version of
linux running on any of my machines to be able to test uCon with a
recent version of wine. As a result, the only test results I have are
with Wine 0.9.24. For that version of Wine, uCon's GUI came up
successfully and much of the feature set worked; however there were
problems. Hopefully much of it is resolved in later versions of wine;
however I am not able to test it. Refer to the WineNotes help text for more information.
Aug 21, 2007:
New -p & -w options to SYSTEM script command so that a command can be run as a seperate process. Refer to the SYSTEM command documentation for more details.
July 27, 2007:
Added a few new formats for line line timestamping.
New 'lntot' subcommand for the FILE script command.
July 12, 2007:
Scripts can call other scripts using the RUN script command; however, if a script is active, then it is illegal to attempt to run another script from the Scripts pull-down menu.
To keep this from happening, uCon grays out the Scripts->Run menu
item from the pulldown menu while a script is active. An alternate
mechanism for running a script is with the function keys or buttons,
and that case did not disallow one script from being started when some
other script was active. This is now fixed, so scripts invoked by
function key or button will be blocked if a script is already running.
July 9, 2007:
Fixed a bug in the script-runner's command line processor, related to dealing with backslash-delimited pound-sign (\#).
June 15, 2007:
Added some help text to SEND script command.
Fixed a bug in the script runner related to long command lines.
Apr 20, 2007:
Updated to release 6.6...
Fixed a few issues with the xmodem dialog box (thanks Joerg!).
Added cumulative transmit and receive character counts to the output of Help->About.
New script command: CD (change directory). Refer to the CD command help text for more information.
New script command: RECV (receive characters). Refer to the RECV command help text for more information.
The SEND and RECV commands populate the SCR_TIMEOUT
shell variable to indicate whether or not a timeout occurred
(applicable only with -t option for these commands).
Added new 'hex' formats (hex0,hex2,hex4,hex8) to the expression evaluator built into the SET command.
Apr 9, 2007:
Fixed a few issues with uCon's telnet client option negotiation.
Mar 22, 2007:
Updated the items in the floating pull-down menu...
Instead of 'Notepad', now 'Editor' will open up whatever
editor you've got configured in the Config->Miscellaneous dialog
Added a new 'Edit Screen Buffer' item which simply combines the steps used to copy screen buffer, open an editor, and paste the screen buffer to that editor.
Feb 13, 2007:
More updates to XMODEM. Added the ability to tell uCon
to validate incoming packets with CRC. Prior to this, uCon's xmodem
receive size defaulted to always use checksum. This adds a new
subcommand (recvcrc) to the XMODEM script command and a new button
(RecvCrc) to the XMODEM dialog box.
Feb 7, 2007:
Yet another fix to the XMODEM script command.
As a result of this bug, there are a few new options to the XMODEM
command because it has to be able to interact with the target similar
to the way SEND has to interact with the target (it typically must wait
for a prompt).
Jan 23, 2007:
Fixed a bug in the console interface caused when focus
transitions between various dialog boxes and the console window of
uCon. In certain cases these focus transitions would cause the cursor
to be erroneously repositioned within the console. Hopefully this is
Jan 22, 2007:
Fixed a couple of bugs that came to the surface in
XMODEM as a result of the recent 1K packet size update. Also added a -d
option to the XMODEM script command to allow the user to control the use of the "delay-between-character" mode.
Jan 5, 2007:
Added 1K send packet size option to Xmodem. Refer to Xmodem help page for more info. This applies to the Xmodem dialog box as well as the XMODEM script command.
Jan 4, 2007:
Updated to release 6.5...
The DHCP server config can now
use shell variables as the arguments. This obviously requires that at
the time of the DHCP server startup, the shell variable must exist.
Added the ability to set a shell variable through the
GUI. This includes some movement in uCon's menu items... Moved the
'Environment' pull-down menu item from 'Scripts->Environment' to
'Config->Environment', and added 'Set and Display' as two
sub-menuitems beneath Config->Environment. The 'Display' item is
what used to be 'Scripts->Environment' and the 'Set' item is a new
dialog box that allows the user to establish/clear shell variables.
New sub-commands to the script command "FILE": 'append' & 'edit'. Refer to "FILE" command within scripting for more details.
Dec 15, 2006:
Added a new script command: BMPVIEW. This is new and
still under development. This commad can be used to display raw bitmaps
of various formats. As of this writing only basic 8-bit grayscale is
supported; however, its simple enough to add additional formats as
needed. Refer to the BMPVIEW help text for more info.
Dec 13, 2006:
1. Apparently, if the COM port number is greater than 9,
then some systems require that the name be altered when passed to
"CreateFile" for opening the port. Instead of COM10, the string is
\\.\COM10. Don't ask me why, but it fixes a bug!!!.
2. If the Config->Backend->Comport dialog box was
used to reconfigure the COM port in any way, it would fail. This was
caused by some new code I added (Aug 25,2006) to better support the
somewhat arbitrary COM port assignments made by USB drivers.
Nov 30, 2006:
Added a -q option to the TIME command so that it can be
"quietly" used to populate the TIME shell variable without dumping
anything to the console.
Nov 8, 2006:
New script command: FSEND. The script equivalent of the Transfer->File dialog box.
Oct 20, 2006:
Added support in the TFTP server for incoming option negotiation. Particularly, the 'tsize' option (RFC-2349).
Sept 22, 2006:
Update to release 6.4...
Added a browse button to the startup dialog box for
retrieval of a pre-built configuration file. This really eliminates the
need for the pull-down menu within that dialog group; however, for now,
both dialog items can be used, with the -Browse- button being more
New script command: TITLE. Simply allows a script to update the content of uCon's title bar. Refer to the TITLE page for more details.
Sept 20, 2006:
uCon now has the ability to receive commands from the moncmd client (part of the MicroMonitor toolset). This
is "still-in-the-works" feature that simply allows a
user to issue commands to uCon via UDP. The moncmd client is a tool
typically used to talk to a MicroMonitor based target over UDP. uCon
now has the receive end (moncmd srvr) built into it so that certain
commands can be remotely passed into uCon via UDP. Refer to the MONCMD server page for more details.
Aug 28, 2006:
The ability to enter a logging tag
applies to both standard and long-term logging, so the dialog used to
enter this tag has been moved from the stanard logging dialog box to
it's own dialog box accessible through the Logging->InsertTag menu item. Refer to the logging help text for more details.
Aug 25, 2006:
Apparently the USB-to-Serial drivers
do not attempt to use the next available COM port. This means that on a
given system that has USB-to-Serial adapters in use, the COM port
associated with any particular adapter could be anywhere in "COMxx
land". This makes it tedious to figure out what COM ports are actually
available on a PC that uses USB-to-serial adapters. To help out with
this a bit, the drop-down menu in uCon's comport dialog box now
attempts to display the status of the COM ports, thus making it a bit
easier for the user to decide which one to attach to. Note that even
though the drop-down label may say it is unavailable, you still have
the option to attempt to attach to it (just in case uCon get's it
Aug 16, 2006:
The content of a clickable button
(i.e. the data that would normally be sent to the backend) now supports
a prefix field that allows the user to use the buttons for things other
than just pre-configured blocks of text destined for the backend.
Currently the only prefix is LTAG, which allows that button to be used
to insert text into the active logging file. I'm sure more of these
prefixes will be added as ideas pop up. Refer to the function key help info for more details.
July 20, 2006:
The clickable buttons now have the "script" option
similar to the function keys. This allows each button to be configured
to quickly enter some configured keystroke sequence or execute a
July 19, 2006:
The long-term logging mechanism in uCon now dumps a few new messages to the log file depending on what has happened...
NEXTDAY: indicates that the log was closed and a new file for the next day is being opened.
TERMINATE:indicates the uCon has been shut down.
NEWFILE:indicates that the current log file was closed in favor of some new logfile.
July 14, 2006:
If the logging toolbar button was clicked to enable
standard logging but there was no previously specified log file, uCon
would just tell the user that a filename must first be established
through the standard logging dialog box.
This is now changed so that if no file is specified when the button is
depressed, it will notify the user and immediately start logging with a
temporary file that can be seen (and later edited) through the standard
logging menu item.
July 13, 2006:
Thanks to an efficiency made in the way uCon highlights
text, the default startup state is changed to have uCon's character
highlighting be enabled. It can still be disabled in the Miscellaneous dialog box.
July 12, 2006:
Fixed a bug that was not allowing uCon to properly terminate (i.e. halt) a script under certain circumstances.
July 6, 2006:
Update to release 6.3...
The DIALOG script command has a new -m option
which allows the script to create a modeless dialog box. This simply
means that the dialog interaction with the user can be set up so that
it allows the user to do other stuff prior to completion of the dialog.
This update allows the user to enable/disable (default =
disabled) uCon's ability to highlight the text on the screen that is
being swiped (and copied) to the clipboard. This is an optional feature
because the current implementation of the highlighting is cpu-intense;
hence, may not be appreciated on older/slower machines. Refer to miscellaneous configuration dialog for more information.
June 28, 2006:
New "if" comparison: sec (string equal to, case insensitive).
New "CONNECT" script command to allow the script to control what backend connection is used.
New -c option to REGEX script command.
New -b option to the FKEY script command to allow this command to support the new buttons.
June 24, 2006:
Added 2 additional rows of clickable buttons as an extension to the set of function keys.
June 22, 2006:
Bug fix: When running with plink as the backend, uCon would hang on certain dialog boxes. This update fixes that problem.
June 8, 2006:
Cut 'n' Paste is getting closer (still needs
work). Looking a bit more like real cut-n-paste. The improvments may
not be enabled in all uCon installations.
Added a configurable inactivity timeout so that uCon can
be set up to automatically disconnect from the backend it is tied to
after some pre-defined number of minutes. Refer to Config->Miscellaneous dialog box.
Added option to Xmodem Send
that, when enabled, will insert the -s ### option into the xmodem
command line (used with uMon's xmodem command) to tell the receiver the
exact size of the file (rather than having the file save at the
May 30, 2006:
One more update to the startup dialog box (to be a bit more intiutive)...
Now there are 4 unique choices for startup: comport
backend, telnet backend, plink backend or pre-existing config file. One
of those 4 is selected, and the OK (or CANCEL) button at the bottom is
used to continue.
May 25, 2006:
New Scripts menu item (Scripts->Environment) to display the current set of established shell variables.
Updated the startup dialog box to support the PuTTY Link backend, and eliminated the ICON and the stuff related to the telnet server (this is done after uCon starts up).
Fixed a few minor bugs in the new plink backend code.
May 17, 2006:
Update to release 6.2...
Made some efficiency improvements to uCon's incoming
character processing and screen updates. This reduces the burden that
uCon puts on the host CPU; thus providing a better interface with COM
ports that are running without flow control.
Also, updated a few of the dialog boxes (TFTP client, TFTP server and FTP server) to support a browse button.
May 11, 2006:
The long-term logging dialog
box now allows the user to specify filename prefix, plus the ability to
browse for the long-term logging directory to be used.
May 1, 2006:
This is an update to release 6.1 and includes the first
(i.e. beta) version of a new Plink backend. This is still very new, so
user beware. The goal is to provide an interface between plink (part of
the Open Source PuTTY package) and uCon; thus allowing uCon to connect
to RLOGIN & SSH servers. Refer to the plink backend help information for more details.
Apr 27, 2006:
Added a new function to the SET command's ability
to process expressions... rand(). This allows the user to load a shell
variable with a random number.
Slight change to symbol processing on the command
line... If a '%' is found on a command line, but there is no SYMFILE
shell variable set, then the string is not processed as a symbol name.
Apr 13, 2006:
Added the ability to capture binary data with standard
logging. A new BIN check box is part of the standard logging dialog.
Refer to logging for more information.
Mar 31, 2006:
Ctrl-V can now optionally be used as a PASTE command (instead of the floating menu item).
Improvements (i.e. bug fixes) made to the accuracy of the "cut" in cut-n-paste when the window is resized.
Fixed a screen refresh problem that occasionally caused
the console window (and the text that would be stored in the buffer) to
Mar 9, 2006:
Update to 6.0...
The TFTP client now supports the "tsize" option in the WRQ. Refer to the TFTP Client documentation for more information.
Cut 'n Paste...
The ability to swipe a block of text from the console
window to the clipboard is now working (note that the cursor over the
console window is now an I-beam rather than an Arrow). When the left
mouse button is depressed and swiped accross some set of characters
within the console window of uCon, those characters are automatically
copied to the clipboard and can be pasted. Currently this only works
for swipes within a single row or line and the group of characters is
only momentarily highlighted.
Also, a block of non-whitespace characters can be copied
to the clipboard with a single left-button double-click over any
character within the block (uCon will then figure out the first and
last character of the block).
For this release (at least), the trace window will show the data that has been copied.
Mar 6, 2006:
Bug fix: tftp client was erroneously updating the
destination file when doing a "get" and the incoming packet block
Mar 3, 2006:
Added a new uMon-specific tool to allow the user to edit a TFS-based ASCII file using a host-based editor. The new uMon->EditTFSFile
menu item assumes the target has an IP address, pulls the requested
file up to the host using TFTP, allows the user to edit it using the
editor specified in uCon, then the file is transferred back to the
target, once again using TFTP.
Feb 21, 2006:
Finally got around to getting the THUMB and MOUSEWHEEL scrolling methods to work.
Feb 9, 2006:
The -t option to SEND now
supports time in floating point notation, so you can specify a timeout
that has a resolution of 100ths of a second. Obviously this is limited
to the accuracy of the PC's internal timer, so it isn't going to be
very precise; however, it does allow the timeout to be much less than
the old minimum of a second.
A similar change has been made to MONCMD. The the -w option supports resolution of 100th's of a second.
Jan 31, 2006:
Update to 5.3...
When uCon's configuration is saved, it includes the
postion (not just the size) of the window so that when restarted it
will come back to the same spot on the desktop.
The LINES shell variable is now loaded with the size (in lines) of the console window.
If the SEND command is configured to wait for a prompt
(via -p or PROMPT shell variable), then SEND will also populate the
shell variable LASTLINE with the most recently received line prior to
reception of the prompt.
Jan 27, 2006:
Added a new script command called REGEX. This command
gives the script the ability to do sophisticated regular expression
processing. Refer to the REGEX help text for more information.
Jan 26, 2006:
Added a new script command called RUN. This command gives the script the ability to call other scripts. Refer to the RUN help text for more information.
Jan 23, 2006:
Added a new script command called FKEY. This command
gives the script the ability to configure all/any of the 9 visible
function keys on the uCon user interface. Refer to FKEY help text for more information.
Jan 13, 2006:
DHCP server has more help text in both this help data
and the default DHCP config file when a new server config file is
created. Also, added support for multiple IPA_xxx option types to be
concatenated on a line. Refer to DHCP server help text for more information.
Jan 10, 2006:
Update to 5.2...
The baud rate can now optionally be specified as user
defined. This allows users to set the baud rate to any value (within
the driver's limitations), not just the standard bit rates. Note that
this is only configurable from the Config->BackEnd->Comport
Scripts can now be paused, resumed and stepped. Added
appropriate additions to the "Scripts" menu item, new "pause", "resume"
and "step" toolbar buttons, and changed the stopsign (used to halt a
script) to a square. Refer to the scripting help text for more information.
Dec 3, 2005:
Added new dialog box type for use with the DIALOG
command in scripts. The new type, DDLIST (i.e. drop-down-list), allows
the script to create a list of choices for the user to pick from using
a drop-down list. Refer to the DIALOG command description for more information.
Nov 26, 2005:
Added new toolbar button to support transmission of the
BREAK state over the COM port. The BREAK is also sent by the
Nov 22, 2005:
Function key labels are now buttons as well, so the user can click on the button or depress the function key.
Nov 18, 2005:
Fixed a few memory leaks that were causing uCon to
eventually hog RAM on a system if left running under certain
circumstances. Also, transitioned over to a MAJOR/MINOR release number
format. This puts us at release 5.1.
Oct 28, 2005:
A new scripting command is available to support the
ability to have one uCon session interact with another. The command is
called TCP, refer to the scripting page for more information.
Oct 21, 2005:
The telnet backend now provides an option to
automatically reconnect to a remote server that may have temporarily
gone down. Refer to telnet backend description for more information on this.
Oct 11, 2005:
The SYSLOG server can now be configured to send its
received packets to the log. The packets can be directed to whichever
log is enabled (standard or long-term). The TFTP, DHCP and SYSLOG
servers can now be disabled without the exiting uCon.
Sep 12, 2005:
uCon can now act as a proxy providing an FTP-to-TFTP
file transfer agent. The idea is simple. For one reason or another you
need to TFTP a file to a target but that TFTP transfer is blocked
(usually due to some kind of firewall issue). Assuming you are able to
ftp into the same site, then you can enable uCon's FTP server, and
transfer the file (using FTP) to the host running uCon, then uCon will
transfer that file to some other machine within it's domain. Refer to
Help->Servers->FTP for more information.
Apr 21, 2005:
When uCon is used as a telnet server (with clients
attached to it for access to the COM port), the running uCon session is
usually not visiable to the remote client (simply because the remote
client is usually distant from the server). In cases when that server
takes some kind of error (shouldn't happen, but it can), the server
would simply lock up and all clients would just hang. This isn't good,
so in the event that an error occurs, the uCon error handler now sends
the message to all attached clients prior to sending it to the local
console by way of a dialog box. This notifies the remote user of the
need to restart the uCon server.
Apr 1 2005:
New toolbar button to loop through the COM port baud
rates. This allows the user to quickly determine the baud rate of the
target connection (if unknown).
Mar 15, 2005:
The dialog boxes used with the DIALOG command (in
scripts) now supports the CLOSE button (top right corner X). This
allows the user of the script to terminate the script at any dialog box
created by the DIALOG command.
Mar 1, 2005:
Added "Moncmd" menu item under the uMon menu list. This
allows the user to issue UDP-based commands to the target running
Mar 9, 2004:
Added a new "ANY" COM port option. If this port is
specified, uCon will look for the first available COM port in the
system. For example, if COM1 is being used, and the "ANY" port is
specified then COM2 (assuming it physically exists) will be opened.
Mar 5, 2004:
Most of the VT100-mode cursor positioning is now
supported. This allows a reasonable amount of support for interfaces
that rely on VT100 terminal emulation.
Feb 19, 2004:
The command line options "-I" (specify uCon's
installation directory) and "-s" (invoke a startup script) have been
eliminated. The "-I" option is no longer needed, and the "-s" option is
replaced with an entry in the Config->Miscellaneous
dialog box. This follows the trend to replace all command line options
with configuration items so that the options can be stored into the
configuration file and are not dependent on command line entry.
Also, the Config->Miscellaneous dialog box has a
"StartupMsg" text box. The content of this box (if anything) will be
posted to the user as a simple message box as uCon starts up.
Feb 12, 2004:
The configuration now includes the window position, so
that after saving a configuration and exiting uCon, when restarted
using the saved configuration, uCon will come up in the same position
on the screen that it was in at the time of the last configuration
save. By default, uCon will come up and allow the OS to position the
window; but once a configuration is saved, subsequent startups of uCon
will start at the active screen position at the time of the last
Feb 10, 2004:
The command line options "-c" (column adjust) and "-r"
(row adjust) are no longer supported. The width and height of the main
window are now part of the configuration that is stored in the config
file. The uCon console window defaults to 80 columns by 40 rows, and
can be adjusted by changing the size of the window through normal
"windows-like" manipulation, then saving the configuration. The height
of the trace window (default = 8 rows) is also a configuration item and
is now handled in the Config->SystemTrace dialog box.
Nov 26, 2003:
There's a new "View" menu item. The items within this
menu item allow the user to remove various portions of the window from
view. The presence of the statusbar, toolbar, function keys and system
trace windows are all configurable through this menu.
Nov 18, 2003:
The window width is now adjustable and new text within
the console window will appropriately be displayed based on the new
Nov 2, 2003:
I had originally configured all servers (excluding the
terminal server) within uCon to require the user to manually enable
them at startup. I did this because depending on how they are
configured, they can be a security risk or, in the case of the
DHCP/BOOTP server, could cause confusion on a network if
unintentionally enabled. On the other hand, for those that regularly
use the servers, it is convenient to have the servers configured to
automatically start up. As a compromise, now at startup, if a server is
enabled in the configuration file, then that server will automatically
be started; however, uCon will post a warning to the user, to verify
user awareness of the fact that the server is running.
Nov 1, 2003:
Updated the "Miscellaneous" dialog box. Mostly just text
changes; however, I added a new checkbox that will cause the ENTER key
to generate both CR & LF instead of just CR.
