[Xastir] Xastir and serial port issues

[Craig Anderson]

You can try:

echo -e “\300\377\300” > /dev/ttyS0

Assuming the baud rate has not changed
out from underneath you on ttyS0.  Sometimes
the above command does not "seem" to work
(minicom still doesn't see any command prompt)
until I power-cycle the TNC, then the firmware
banner and command prompt comes right up.
