The HDA card softmodem chip is 0x1025:0110
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.tar.gz having a compiled slmodemd. Unpack
under Linux with:
$ tar zxf SLMODEMD.gcc4.tar.gz
and read instructions therein. But briefly, the modem is setup with
command:
sudo 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,

[strange enough]:
I had an hard time configuring audio on this laptop (Acer TM 2482WXMi),
till I discovered I had to unmute the "surround" channel in alsamixer.
Is this issue relevant to the modem (maybe I have to unmute some other
strange channel)?
TIA,
Giuseppe
