Linmodem doesn't work out the box with anything. linmodem was abandoned 
by its author at a very early stage, before any of its component parts 
really worked.

It has a number of useful bits, which might be used as the basis for a 
modem. It does not have a properly working code for any of the modem 
standards.

I think Fabrice got busy, and with patent issues preventing wide 
deployment of a V.34 modem finished the software just seemed like a 
waste of time to him. He is one of the good guys of free DSP, and has 
since produced several valuable things which are complete.
