[Xastir] pipe as TNC device?

[Alex Carver]

Best thing to do would be to use the microcontroller to send the data out ethernet, one TNC per TCP port.  Then you can create one instance of socat per TCP port which then creates one device per TNC on the machine.

So say three TNCs on your uC.  Have port 5001, 5002, and 5003 connected to TNC 1 through TNC 3 respectively.

Then on the Xastir machine you only have to do:


socat PTY,link=/home/user/ttyS11,raw,echo=0 TCP4:microcontroller:5001 &
chmod a+rwx /home/user/ttyS11

socat PTY,link=/home/user/ttyS12,raw,echo=0 TCP4:microcontroller:5002 &
chmod a+rwx /home/user/ttyS12

socat PTY,link=/home/user/ttyS13,raw,echo=0 TCP4:microcontroller:5003 &
chmod a+rwx /home/user/ttyS13


And then start Xastir with a TNC pointed to each of those ttyS1x
