I had the idea the other day that you could theoretically implement a
Winmodem driver as a JACK client. All you would need is an ALSA driver
that exposes the hardware part of the modem as a sound card, a mechanism
to inject the resulting bits back into the kernel networking layer, and
the DSP knowledge to implement a software modem...
This is almost completely pointless, but might be an interesting CS
project.

Hey Lee,
I was thinking about this a little bit and it's probably easier than it
sounds.
I thought that Alsa already supported MC97 based AMR modems? It looks
like it does with the SND_INTEL8X0M module ..
Also, you wouldn't have to worry about injecting stuff into the
networking layer since modems are just character devices in linux.
The only real part would be the DSP stuff. Their might be some other
projects to do this kind of stuff already ..
later,
Steve

the slmodemd is already a user space app.
and it has an alsa mode already. though it did not work when i tested
it.

slmodem is for SmartLink modems (it has this in licence) and it contans
binary part - it can not run on PPC or other processors.
I've seen somewhere project to write software modem, but it was not
finished and abandoned.

Hi,
It would be fantastic if that crazy idea could be done! In my opinion a
big limitation for greater adoption of linux on third world countries
like Colombia where a broadband connection is still a luxury, is the
limited modem support.
I recently tried to find linux compatible modems and it was impossible
(or too expensive -around US$50) in the local market, so I had to ask my
brother (who lives in the US) to get me one from ebay which can cost
around US$15 incl. shipping.
Cheers,
Andrés
