Hi everyone,
My question is actually fairly specific. Thanks to the excellent guidance I received from you a couple of years ago, I've been happily using my intel-chipset (ALSA) linmodem on SuSE 10.2 on a daily basis - and having just decided to take the plunge and upgrade to Ubuntu 8.04, I made it my top priority to get my linmodem drivers up and running again on the new installation. Just to be safe, I downloaded and ran the ScanModem script, which told me that I needed exactly the same driver I had used on the old system (surprise). Once I downloaded and installed the newest version of the pre-compiled slmodemd program, however, I was dismayed to find that an error I had never seen before now appeared every time I tried to run slmodemd. And when I tried to dial out in spite of the error, wvdial promptly and unfailingly exited with a "NO DIALTONE" message. (See attachment for details)
Additional info:
Appending X3 to the init code didn't help; in fact, having "listened in" on my computer while it was ostensibly dialing out (by picking up the phone), I can tell you that it didn't seem like the modem was actually communicating with the phone line at all (I didn't hear anything but a dialtone),
Just for fun, I tried reloading the ALSA drivers - only to be told that the particular component slmodemd apparently depends on (snd-hda-intel) couldn't be unloaded. The same thing happened with modprobe -r snd-hda-intel.
Any thoughts would be greatly appreciated
- Jordan

the package SLMODEMD.gcc4.2.tar.gz having a compiled slmodemd. Unpack under Linux with:
$ tar zxf SLMODEMD.gcc4.2.tar.gz

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.2.3
and the compiler used in kernel assembly: 4.2.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.2
linuc_headers base folder /lib/modules/2.6.24-19-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 needed. 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

In case of an "error 17" "serial loopback" problem, see:

To enable dialout without Root permission do:
$ su - root (not for Ubuntu)
sudo chmod a+x /usr/sbin/pppd

sudo chmod a+x /usr/sbin/pppd
