summary: Agere, modem stopped working with new ALSA
I might have nearly the same software/hardware
configuration as that reported by pablo@xxxxxxxxxx on
this list on 15 Feb 2007 (but amd64) and the same
failure after upgrading alsa:
# ./slmodemd -c USA --alsa hw:0,6 SmartLink Soft
Modem: version 2.9.11 Mar 13 2006 18:27:33

modem `hw:0,6' created. TTY is `/dev/pts/6'
Use `/dev/ttySL0' as modem device, Ctrl+C for
termination.

Lacking a dsp (digital signal processing) chip, the
modem is a
software
intensive or "softmodem" type. Its primary controller
manages the
traffic
with the CPU. But the software needed is specified in
the Subsystem.
-----------------------------------------
Support type needed or chipset: slmodemd
An ALSA (Advanced Linux Sound Architecture) modem
driver:
snd-hda-intel
provides Low Level support enabling contact with the
modem hardware.
For all BUT Conexant chip soft modems (using hsfmodem
software)
complementary High Level support is through a
Smartlink utility:
slmodemd
Download from
http://linmodems.technion.ac.il/packages/smartlink/
the package SLMODEMD.gcc4.1.tar.gz having a compiled
slmodemd. Unpack
under Linux with:
$ tar zxf SLMODEMD.gcc4.1.tar.gz
and read instructions therein. But briefly, the modem
is setup with
command:
slmodemd -c YOUR_COUNTRY --alsa hw:0,6
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read Smartlink.txt and Modem/YourSystem.txt for
follow through
guidance.
Already loaded into the kernel is snd-hda-intel and
audio drivers it
depends on,
