This is really just a note to myself in case I ever have to get a TNC out of kiss mode again. Tried using the Xastir kiss-off.pl script as well as a number of other things. Finally was able to get it out by using the following command:
echo -e ‘\0300\0377\0300’ > /dev/ttyUSB0
Also working with Direwolf to feed Xastir there are a number of commands. The two that seems to work best are as follows:
rtl_fm -f 144.80M – | direwolf -r 24000 -D 1 –
rtl_fm -f 144.39M -p 20 -o 4 – | direwolf -t 0 -n 1 -r 24000 -b 16 –
