Okay, long time PAT user, usually used with HF and ardop. Works like a charm, and hats off to all the great devs and development in this!

That said, I can't make ax25 and packet work worth a hoot in PAT. So, after days of trying this out, I decided to read through all of the posts here that mention ax25, and none of them solved my issue. So, I decided it was time to ask for help. Maybe you smart folks can point out what I'm doing wrong.

Hardware Setup:
TS-700A 2m radio, signalink USB, Panasonic laptop.

With this laptop I can dual boot Windows or Linux. In Windows, I can use Soundmodem and RMS Express and hook right up to a local winlink station: KL7EDK-10. No issues, works out of the box.

Without changing any dials on the radio or signalink, if I boot into linux, it all falls apart.
Software setup:
Ubuntu 22, Direwolf 1.6, PAT 12, or 12.1, or 13.0 (tried several to be sure).

Direwolf conf:
alaskalinuxuser@alaskalinuxuser-CF-52NKE102M:~$ cat direwolf.conf
# My direwolf config

ADEVICE - plughw:3,0

ACHANNELS 1

CHANNEL 0

MYCALL KL4TH-0

MODEM 1200

#TXDELAY 500
#TXTAIL 50

AGWPORT 8000
KISSPORT 8001

IGTXLIMIT 6 10

==============
/etc/ax25/axports:
alaskalinuxuser@alaskalinuxuser-CF-52NKE102M:~$ cat /etc/ax25/axports
# /etc/ax25/axports
#
# The format of this file is:
#
# name callsign speed paclen window description
#

#1    OH2BNS-1    1200    255    2    144.675 MHz (1200  bps)
#2    OH2BNS-9    38400    255    7    TNOS/Linux  (38400 bps)
wl2k KL4TH-1 1200 255 2 wl2k (1200 bps)
=================
So I run direwolf, kissattach, and pat like so:
$ sudo direwolf -t 0 -p
$ sudo kissattach /tmp/kisstnc wl2k
$ pat --listen "ax25" http

And it seems to work, I send out some ax25 signal, the other station responds audibly. I can hear it, but I never connect. The terminal for direwolf looks like this:

<<< Data frame from KISS client application, port 2, total length = 18
  000:  20 96 98 6e 8a 88 96 f4 96 98 68 a8 90 40 61 3f   ..n......h..@a?
  010:  70 9b                                            p.
[0L] KL4TH>KL7EDK-10:(SABM cmd, p=1)
[0L] KL4TH>KL7EDK-10:(DISC cmd, p=1)
[0L] KL4TH>KL7EDK-10:(SABM cmd, p=1)
[0L] KL4TH>KL7EDK-10:(SABM cmd, p=1)
[0L] KL4TH>KL7EDK-10:(SABM cmd, p=1)
[0L] KL4TH>KL7EDK-10:(DISC cmd, p=1)

I hear my station transmit with another 2m handi, I hear the response from the other station, but we never connect. Any thoughts?

Also, I tried pat-gensio, but I just get an error every launch about cannot find a value or file?

Hopefully you guys can tell me how dumb I am and point me in the right direction, or I'll be lost wandering around in the great Alaska wilderness when the snow comes. :D

To state the obvious, it looks like direwolf is not hearing anything from the other end.  Have you checked the receive sound levels in linux?

I also have an odd thing with my system, when it boots under Linux it always wants to take the radio soundcard as the main one and I have to fix it every time I boot.  Check the sound config under settings.

Outside of that, I have run soundmodem in wine on Linux; that might be something to try.  Other than that, this is kind of odd.

What's the gensio line?
