Script Command: COMPORT
COMPORT [BREAK | DTRTGL | baud]
If the argument is the string "BREAK", then send a BREAK to the COM port.
If the argument is the string "DTRTGL", then toggle the state of DTR on the COM port.
Else, assume the argument is a baud rate and re-define the baud rate of the COM port.
Valid values are 9600, 19200, 38400, 57600 and 115200.
If no argument is specified, then the current baud rate is returned. The value is also placed in the BAUDRATE shell variable.
