TM
3.32 TRANSPARENT MODE
TM [<port>][<escape>]
The TM command connects the console serial port and the host port together, allowing the user
to communicate with a host computer. A message displayed by TM shows the current escape
character, i.e., the character used to exit the transparent mode. The two ports remain connected
until the escape character is received by the console port. The escape character is not transmitted
to the host and at power up or reset is initialized to $01=^A.
The optional port number allows the user to specify which port is the host port. If the port
number is omitted the default is port 1. The port number must be within the range 0 to $1F.
Ports do not have to have the same baud rate, but for reliable operation the terminal port baud
rate should be equal to or greater than the host port baud rate. Use the PF command to change
baud rates.
The optional escape argument allows the user to specify the exit character. Use one of three
formats:
ascii code
ascii character
control character
If the port number is omitted and the escape argument is entered as a numeric value, precede the
escape argument with a comma to distinguish it from a port number.
