If you've set up AX.25 kernel networking configured/working then you
should use "AX25 TNC" in Xastir. This is the more complicated
setup. In this case the "listen" command when run as root should
see packets and the "beacon" command should cause a transmit. In
other words you can test out the receive w/o Xastir. This setup
allows you to share the TNC across many applications.
If you only want to connect Xastir to the TNC (won't be sharing the
TNC with other apps) and don't have an AX.25 kernel networking port
configured then use the "Serial KISS TNC" interface instead. In
this case DO NOT enable the "Init KISS-mode on startup" button as
that's for a specific TNC used in Europe only.
I'm using the "Serial KISS TNC" setup currently with a TNC-X at
home, but have used the "AX25 TNC" configuration before as well.
