Hi all,
I have been using slmodem-2.9.11-20051101 for years on a Fedora Core 2 system.
Since I got plenty of good advice that I should upgrade, I finally
installed Ubuntu 7.10 ......
I only could get an antiquated
sl-modem-daemon_2.9.10+2.9.9d+e-pre2-5ubuntu4_i386.deb.
I know from before that I need 2.9.11 to access my usual ISP which
requires slmodem option -ringdetector. I could not connect even to a
normal ISP anyway with the above package. So I uninstalled it, though
the snd-via82xx-modem module is still loaded at startup I don't know
how.
Now I just would preferably if possible forget about this alsa driver
whose configuration seems so complicated, and that I could not get to
work anyway and only use slmodemd like I did before.
The README in slmodem-2.9.11-20080417 specifies that alsa drivers are
not mandatory, and even that slamr is more stable and has more
features.
I could not compile slmodem-2.9.11-20051101 on linux
2.6.22-14-generic that comes with Ubuntu 7.10 but
slmodem-2.9.11-20080417 compiled like a breeze.
Everything looks OK in ModemData.txt doesn't it ?
But then I cannot keep a connection, even to a normal ISP without -ringdetector.
- Using wvdial I may get "no dialtone", "no carrier", or else ppp
loads and then dies after a few minutes (no response to 4 echo
requests) of an extremely slow connection at best. I tried playing
with some options in wvdial.conf, it did not help.
- /dev/slamr? get erased from time to time
- even /dev/modem gets erased
- I noticed that /dev/ttySL0 points to new /dev/pts/? each time I run slmodemd.
Thanks in advance for any help, and congratulations to the authors of
this very helpful site. It is such a bore when you have to log out and
start WindowsTM just to access the internet.
PS I am in Italy, using Teleconomy Internet as ISP, in case someone
knows about it.
Cheers,
AO

An ALSA (Advanced Linux Sound Architecture) modem driver: snd-via82xx-modem
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:
sudo slmodemd -c YOUR_COUNTRY --alsa modem:1
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read DOCs/Smartlink.txt and Modem/DOCs/YourSystem.txt for follow
through guidance.

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.3
and the compiler used in kernel assembly: 4.1.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.22-14-generic/build
However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed
in /usr/include/ .
For martian_modem, additional required packages are libc6-dev (and
for Debian/Ubuntu,
linux-libc-dev). The also required headers of package libc6 are
commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev
packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at
http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.
If a driver compilation fails, with message including some lack of
some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include.
The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb

To enable dialout without Root permission do:
