  Bring up the AX.25 interface
  • Before you start, ensure that your TNC is in KISS mode.
    OPTION 1: Via systemd
    The deb-package comes with a set of scripts to help you manage the AX.25 interface. If you're not running a systemd capable system or did not install Pat via apt, you should skip to option 2 (manual).
  • Install the systemd script:
    $ sudo /usr/share/pat/ax25/install-systemd-ax25-unit.bash ... successful
  • Edit the device settings:
    $ sudo nano /etc/default/ax25
  • Bring up the device:
    $ sudo systemctl start ax25
    Check status/error log:
    $ sudo systemctl status ax25 -l
  • (optional): Enable the AX.25 interface on startup
    $ sudo systemctl enable ax25
  • If everything went fine, you should be ready to use Pat with your newly configured axport.
  • When done, to bring down the interface:
    $ sudo systemctl stop ax25

  • OR: Option 2 - Manual:
  • • Attach axport wl2k to the KISS TNC at /dev/ttyXX:
      $ sudo kissattach /dev/ttyXX wl2k
    • Set kiss params (txdelay 300ms, txtail 10ms, persist 80 and half duplex) for port wl2k:
      $ sudo kissparms -p wl2k -t 300 -l 10 -s 12 -r 80 -f n
    • The AX.25 port should now be ready for use.
      When you're done, bring down the interface with:
      $ sudo killall kissattach
