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-1.0.13.tar.gz having a compiled slmodemd. Unpack under
Linux with:
$ tar zxf SLMODEMD-1.0.13.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,

Versions adequately match for the compiler installed: 4.1.2
and the compiler used in kernel assembly: 4.1.2
Kernel-header resources needed for compiling are not manifestly ready!
If compiling is necessary packages must be installed, providing:
