Problems with Kissattach

Hello Nvidia team,

I am trying to get a set of apps loaded and configured on my Jetson Nano (4gb version). I am running Ubuntu 18.04-LTS. I have successfully compiled and installed Direwolf and Pat Winlink. I also used the “sudo app-get install” command on ax25-tools and ax25-apps. These commands seem to work fine.

When I attempt to use the “sudo kissattach /tmp/kisstnc wl2k” command I get this error:
“kissattach: Error setting line discipline: TIOSETD invalid argument
Are you sure you have enabled MKISS support in the kernal
or, if you made it a module, is that module loaded?”

Searching the internet for a resolution for this issue led me to some suggestions to add mkiss and ax25 to the “/etc/modules-load.d/modules.conf” file, but this does not seem to resolve my issue.

Thank you in advance for any suggestions you have on what I might try next.

Kind regards,
