Here's some of my /etc/ax25 scripts. Soundmodem works FB with Kernel
2.0.36 patched on a SuSE (www.suse.com) 6.4 box as well as with newer
2.3 (and 2.4?) kernels. I even have Soundmodem, LinPSK and a whole
portable ax.25 node all in a teeny "notebook" form factor.

Note: this works FB with Baycom serial drivers, so you really can run
a hub from a notebook PC!

This is how I start packet networking on my server box. It's main
function, other than a DOD internet router, is a CLX DX Packet
Cluster.

Try some debugging flags and mail me your /var/log/warn &
/var/log/messages files if you still have difficulty.
