Greetings to all,

This is for JNOS 2.0g or later - linux only (sorry) !

I have a working 'attach baycom' interface. The old way of using
pseudo-tty with the net2kiss software is no longer required.

1. Disclaimer and System Requirements

This prototype was written on a slackware 9.1 system, 2.4.22 kernel, which
came with the baycom_ser_fdx module already. Of course you will need kernel
headers and development. If you are trying this on another system, results
may vary. If you feel like you need a challenge, then go for it, and let
me know (we can work on it together).

I am using the 'baycom_ser_fdx' module (device name bcsf0) !

2. Preconfigure the kernel module

   a) load the kernel modules first (as root) - for my system (ttys0) :

       modprobe ax25

       modprobe hdlcdrv

       insmod baycom_ser_fdx mode="ser12*" iobase=0x3f8 irq=4

      you can determine this by 'cat /proc/tty/driver/serial'

   b) you MUST make sure that the kernel interface is *up*, using :

       ifconfig bcsf0 up

      only then will the 'attach baycom' command work. If you fail to do
      this, then the JNOS 'baycom_rx' process will terminate everytime
      you try and do an attach, and nothing will work.

3. How to attach from within JNOS

attach baycom vhf 300 bcsf0
pause 2
ifconfig vhf description "1200 baud on 145.01 Mhz"
param vhf 2 256
param vhf 3 1
param vhf 5 1
param vhf TxDelay 20

4. Closing comments

This works REALLY REALLY well on my system at home. I'm very pleased !
