New to the list...

[IT3 Stuart B. Tener, USNR]

List members:

	I am new to the email list, and would like to ask a few questions.
Is there a website that allows me to set and control the options I have for
this email list?

	AX.25/Linux questions!

	I have been a System Administrator and a Ham for over 15 years each,
and I am trying to get AX.25 + Linux working, so here we go. By the way in
case it interests anyone I have read the AX.25 FAQ (did not understand all
of it, but I did read it). I think the FAQ is very poorly organized but in
terms of the technical data, I understand it.

	Now it is my goal to get Linux running using the AX.25 drivers. When
I do I, eventually I would like to build my own TNC using one of these
single board computers, such as openbrick. But, that is after I make it work
on the desktop I have (and my laptop).

	I have a few questions for you now:

	If my goal is to configure TCP/IP over a soundcard modem using
Linux, what do I need to get working (using the AX.25 FAQ as a guide)? For
example it is my understanding using a TNC, you would put the TNC into KISS
mode to allow TCP/IP to avoid the AX.25 level. Then setup (in the old days)
KA9Q to do the TCP/IP stack.

	The first thing I would like to accomplish is making the PC act as
an AX.25 TNC using the soundcard. Once this works (for basic packet
operation) then I would like to configure the system to:

	(a) Run TCP/IP, using the soundcard as the modem
	(b) Run TCP/IP, using an external TNC in KISS mode (on /dev/ttyS0)

	I did the modprobe of soundmodem, and then tried to issue the
sethdlc command, but after doing so I got "no such address or device" when I
did an "ifconfig sm0 up".

	How can I verify what the IO, DMA and IRQ of the sound card is, if
it is built into the motherboard, and the BIOS offers now way to set those
for the card?

	Other than the soundcard not being set right by sethdlc, I am lost
as to what is wrong. Any assistance you can offer would be well appreciated.

	Thanks in advance.

You may be able to get this information from /proc/pci.

As well as the sound card parameters, you use sethdlc to configure how
you will key the radio - serial port, parallel port or MIDI port. I
think an error with those settings can also result in an error at 'up'
time.

Perhaps you should try the AX.25-HOWTO first.

Well, what kind is your soundcard? Notice that the kernel 
soundmodem (the module you're trying) only supports Sound 
Blaster o Windows Sound System compatible cards. Many new 
cards are not suported by it.

But haven't you heard about the userspace soundmodem? It is 
not a kernel module, it's a usermode program, it's easier to 
configure, and (the most important thing) it handles the 
soundcard through OSS, so it works with virtualy every 
soundcard supported by OSS.

It's likely that your onboard soundcard will not work at all 
with the kernel soundmodem.

Try usermode soundmodem, and tell us.
