WIN MODEM?

[Bob]

Greetings -  As a real newbie a dumb question.  I appreciate what has
become to be called the WIN MODEM which will only work with WINDOWs
because part of the modem activity is being performed by the driver
software which is specific to that OS.  Given these modems are some what
cheaper and seem to work just as fine is there a LINUX driver to do this
modem "function"?  Maybe such a bit of software is being considered.
Seems such a need exists.

Or, am I missing the point here?

Thanks for the read.

Bob
