Using ax25ipd

["Charles Boling (AD7UF)" <junk07+ham@boling.us>]

I've done the soundcard driver.  I've done the BPQ driver.  I've done
NET/ROM.  I've done a basic node.  And now I've done gotten myself
stuck! :-)

I want to use ax25ipd to establish an AXUDP tunnel over the Internet.

Unfortunately, all of the documentation I've been able to find so far is
either obviously outdated (e.g. from 2000, uses old-style BSD
pseudo-TTYs), or otherwise doesn't work (e.g. expects ax25ipd to
immediately write data to stdout after launch, as in
  http://mailman.f6fbb.org/pipermail/xfbb/2012-March/004316.html)

Add to that the fact that I'm really green on pseudo-TTYs, kissattach, etc.

Here's what I have in axports:
 sm0	AD7UF	1200	255	2	SignaLink USB
 bpq0	AD7UF-9	1000000000	255	5	BPQ node for eth1
 axudp	AD7UF-12	115200	255	5	AX25 over UDP (ax25ipd)

and here's what's in ax25ipd.conf:
 socket udp 10093
 mode tnc
 mycall ad7uf-12
 device /dev/ptmx
 speed 115200
 loglevel 4
 broadcast QST-0 NODES-0 ANYONE-0
 route ke7awr ke7awr.no-ip.org udp 10093

After launching ax25ipd, I see this logged:
 14:47:48  ax25ipd: #012Current configuration:
 14:47:48  ax25ipd:   socket     udp on port 10093
 14:47:48  ax25ipd:   mode       tnc
 14:47:48  ax25ipd:   device     /dev/ptmx
 14:47:48  ax25ipd:   speed      115200
 14:47:48  ax25ipd:   loglevel   1
 14:47:48  ax25ipd: #0121 active routes.
 14:47:48  ax25ipd:   KE7AWR#01124.21.99.210#011udp#01110093#0110
 14:47:48  ax25ipd: #0120 parameters

What now?  Do I need to use kissattach to attach to the other end of the
pseudo-TTY?  Which one?

Of course, without the missing piece, I get this:
 axcall axudp ke7awr
 axconfig: port axudp not active
 axcall: invalid port setting

Any help would be greatly appreciated!
