# Wrote a small script to get the shittie PTS to a file where its belongs.
# Yes you can also use the agw driver from Direwolf for Jnos.
# Now its also possible to "sed" the right PTS to your ax25 start file
#
# socat -d -d -lf /tmp/socat.pts PTY,link=/tmp/kisstnc TCP4:127.0.0.1:8001 &
# sleep 2
# grep -o "/dev/pts/." /tmp/socat.pts > /tmp/devs.pts
# attachthem () {
# read PTS1
# sed -i "s,kissattach -m 256 /dev/.*$,kissattach -m 256 $PTS1 ax0 44.137.31.73," /etc/ax25/ax-start
#
# }
#
# tail -n 1 /tmp/devs.pts | attachthem
# rm /tmp/socat.pts
# rm /tmp/devs.pts
# sleep 3
#
# Or use it with (X)net.
# sed -i "s,attach sdev4 kiss 4 1 19200 /dev/.*$,attach sdev4 kiss 4 1 19200 $PTS1," /usr/local/xnet/AUTOBOOT.NET
#
# Or with BPQ
# sed -i "s,COMPORT=/dev/.*$,COMPORT=$PTS1," /usr/local/linbpq/bpq32.cfg
#
# Oo well maybe work this better
# IPADDR=127.0.0.1
# TCPPORT=8001
#
# Yes there are many way`s to do this, but i had some fun to play with it.
# Maybe it is useful for someone.

The scipt…. Small but work quit well

This is what i found in the change.log of Jnos

Better support for PTY98 (/dev/ptmx, /dev/pts/N) pseudo devices. Bob (VE3TOK)
   asked for this a long time ago, so I figured I better get it implemented.

   Note : Technically one can use the new jnos 'attach baycom' and go direct to
   a kernel KISS type interface, meaning you don't need to run an intermediary
   program (kissattach or net2kiss) anymore. Try it, let me know how it works.

   COMPILE : Make sure '#define JNOSPTY98' exists in your config.h file.

   The best way for me to show how this feature works is by example. One way of
   getting JNOS to use a linux AX25 device is through the 'kissattach' program,
   but get the one from F6BVP (it has a mod that actually outputs the name of
   the slave device after you run the program). The stock ax25 utilities will
   not tell you that (you have to look for a new /dev/pts/N to appear then).

      kissattach /dev/ptmx radio > /jnos/spool/ptmx_radio.cfg

   The issue here is you don't know what slave device you will get, it could
   change each time you run kissattach, there may be no consistent device name
   for you to depend on when running 'attach asy' in the JNOS autoexec.nos.

   Now in JNOS (autoexec.nos), suppose we have this entry below :

      attach asy ptmx_radio - ax25 ax0 4096 256 9600

   I have added a feature where if the 3rd argument starts with 'ptmx_', then
   JNOS will look for a corresponding *.cfg file, and extract the slave device
   name from it, and then attach using that instead of the original argument.

This is some monitor output of Direwolf.
