Hi,
I'm trying to get the modem in a 'Samsung M55-Pro T7200' notebook to
work.
When using the alsa driver, slmodemd starts fine with
Mar 18 20:09:58 peano slmodemd: symbolic link `/dev/ttySL0' ->
`/dev/pts/1' created.
Mar 18 20:09:58 peano slmodemd: modem `hw:0,6' created. TTY is
`/dev/pts/1'
Mar 18 20:09:58 peano slmodemd: Modem device: `/dev/ttySL0'
However, when I try to dial out I get the following
[root@peano Modem]# wvdial T_Online
--> WvDial: Internet dialer version 1.54.0
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ

ERROR
--> No Carrier! Trying again.
--> Sending: ATDT0,1,9,10,1,1
--> Waiting for carrier.
ATDT0,1,9,10,1,1
NO CARRIER
and in /var/log/messages there is the error message
slmodemd: error: cannot setup hw params for playback: Invalid argument
hda-intel: invalid format_val, rate=9600, ch=1, format=2
I also updated the alsa driver to 1.0.14rc3 (from atrpms) but this
didn't change the behaviour.
With the slamr driver (built from an adapted SRPM from Andreas
Thienemann's page) I get the error
slmodemd: error: mdm setup: cannot open dev `/dev/slamr': No such device
So, I'm really stuck. What options are left?
Thanks.

-------------------------------------------
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,
