You might want to make sure that no other program is using the serial 
port at the same time first and that the serial port settings are ok. If 
someone is using the serial port at the same time, command "fuser -v 
/dev/ttyS1" should display some information on the program. Something 
like "stty -F /dev/ttyS1 sane raw xxxxx", where xxxxx is the serial port 
speed of the TNC, should set some reasonable defaults for the serial 
port. Then send something like "echo -n -e '\300\377\300' >/dev/ttyS1". 
\300 is 0xC0 and \377 is 0xFF.
