A Winmodem is a combination of hardware known as chipset
(much less than in a true pure hardware
modem) and software
(written for the infamous Windows operating systems family).
A Linmodem is a Winmodem working under the famous Linux operating system.
LTmodem stands for a family of widely used, albeit now becoming obsolete, Winmodems built around some Lucent
(now Agere) DSP only chipsets.
An LTmodem is only one variety among many different incompatible Linmodems!
The material presented here is aimed at transforming
the Winmodem which
you have purchased (often without knowing, just plugged in your box by the
manufacturer or the dealer) into a working Linmodem (hardware unmodified, of
This is not the place to look for help with purely hardware (including external), nor xDSL,
This is also not the place to look for help with setting up a connection with
your Internet Service Provider (ISP) -- although some Linmodems specific aspects
of such a connection can be found here (see
post install help).
Nor is this the place to ask which modem to buy. For that purpose see
Rob Clark's Database
with one remark. PCTel based modems shown as supported in that table are supported for
2.4 kernels, but not all of them are supported under 2.6 kernels.
Moreover, this is not the place to look for other help with Linux -- except of course
for issues specific to linmodems only.

Linmodems.org, the Mother page of
this project, is the very first thing to read, before asking questions to
our discussion list such as how to unsubscribe for example.
- "Which chipset in my modem?"
Beginners:please read this first.
You can quickly identify PCI modems chipsets and recommended
drivers, and find installers, by downloading
the most recent version, if not already done today, of
a script by Marv Stodolsky, stored
compressed to avoid potential mistakes if downloaded under some "Other" system
In your own interest, never use an old scanModem nor any scanModem downloaded from any other site.
Since you have just downloaded scanModem, download
unloading, which you may well need later if you install the alsa based slmodem driver.
How to use scanModem:
Beginners may want to read the scanModem
Do not try to decompress nor run
scanModem under any system except Linux!!
After decompression (command gunzip scanModem.gz ), do not
forget to make it executable with chmod +x scanModem, and then
launch the command typing ./scanModem , or trigger it
with source scanModem .
scanModem writes files full with information in a new subdirectory named Modem .
Some of the tests may require to run scanModem as a superuser, which you can do as follows:
- By logging in as root if you are not a Debian/Ubuntu user.
- By becoming root while already logged in as a regular user, if
you are not a Debian/Ubuntu user. The command to achieve that is su
(avoid using su - here, just su, or you will need to type the full path to scanModem).
- If you ARE a Debian/Ubuntu user, use the syntax sudo ./scanModem
For your convenience, see typical scanModem
These files are frightening for a newcomer, so if you do not
understand them, send the file ModemData.txt
and only that file to
our discussion list and volunteers will help you.
