Now that you fixed one if the problems which made slmodemd fail...
(One needed to do the SETFD ioctl _before_ the SETINFO, otherwise
the audio driver wasn't set to full-duplex correctly.)
I still didn't even manage to dial a phone number through the soft
modem up to now (but I couldn't invest much time yet). There
are still some quite serious problems:
-The frequencies (analyzed DTMF tones coming out at the other end)
 are off by about 20%. If I set the sample rate to 9600, it looks
 pretty correct. The driver needs a modification to allow this.
-I'm not sure whether some in-kernel rate conversion gets in between.
 We should make sure that doesn't happen, it probably doesn't do
 any good. The code is rather confusing, and it is probably not worth
 investing time here because the audio middle layer is being reworked
 anyway.
-The gain/mixer stuff has problems: The mapping of 4-bit
 hardware values to the user visible 0..255 range loses a bit
 somewhere, and settings get lost on SETINFO calls unexpectedly.

While I like both beer and the Fundy area a lot, my day job doesn't
leave me as much time as needed for that atm, unfortunately.
