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 course).

This is not the place to look for help with purely hardware (including external), nor xDSL, modems.

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.

New Linux Users,

do not miss The Linux Cookbook.
It is available on line.
You will bless yourself for keeping a printed copy on your desk.

For very impatient very beginners, please at least read this to learn a few very basic commands. We cannot answer questions at such a level. No time, no manpower. Please bear on us.

Windows users new to Linux,

this guide by Mark Chapman is likely to be of great help to you. (note 1/8/01 by J.G.: page 13 of this (PDF) document contains a wrong link to Rob Clark's winmodems database)
Furthermore the link to the PDF guide quoted in the document is broken. Here is the said PDF document .
Unfortunately the brief guide above (not PDF) by Chapman has disappeared so instead I recommend this one. Give yourself a chance, take 10 minutes to read it! You will thank its author.

Learn UNIX, learn LINUX

Both use the same concepts and the same commands.
One is proprietary, the other is free
And the key to success is in Mark Sobell, "An introduction to System V".

And finally

How to start dealing with your modem.
with a mini tutorial for absolute pedestrians about driver compilation.

So, what next (aka the real job) ?
