Soundmodem under 2.4.22

Soundmodem under 2.4.22

[IT3 Stuart B. Tener, USNR]

Linux Hams:

	I am running RH 8.0, and have installed the models for AX25 into the
kernel (not as modules, monolithically), and do not get any "sr0" device if
I do an "ifconfig -a"; why?

	I want to have both my sound drivers (Maestro3) available as well
the ability to run AX25 via the sound card. Do I need to make them both
modules when I compile?

	How do I switch between normative sound card functions and AX25
setup for doing ham radio?

	Why do I not see an "sr0" in my "ifconfig -a"?

	Oh, and by the way, I read the FAQ, it refers to olde kernel
versions, and I am not even sure if it applies to current kernels. As well
what I need is more of a trouble shooting guide, as the kernel stuff seems
to setup in a proper way, since the kernel compiled fine.

	Any ideas?

	Thanks in advance!

Some kernels don't allow renaming interface names, so with usermode
soundmodem the devices may be named ax0 ax1...

You should use the usermode soundmodem variant, then you only need the
maestro3 kernel driver

starting/stopping the soundmodem daemon

What would be even cooler, but may be impractical, would be to have
the soundcard receive/send AX.25 1200 baud on one channel, and be
able to speak using Festival on the other channel.

That would give Xastir users the speech output plus the TNC
functionality with no external hardware other than the PTT circuit.
It would alleviate the need for the external TNC in my vehicle.

Probably not easily possible though, right Thomas?

Other possibilities that might be useful (albeit impractical):

1.  Run two separate soundmodem apps (e.g., 1200/9600), one on each
channel?

2.  Run soundmodem on one channel and a PSK31, etc. app on the other
channel?

This should be possible using ASLA drivers and an appropriate .asoundrc

BTW, that would be really interesting if the various digital apps around 
here were converted to JACK! http://jackit.sf.net instead of boring OSS.
That would give us a lot of flexibility, if you see what I mean...
