WinModems (just like all software-based modems) require software
to run. This software is the "brains" of the modem, unlike a
hardware-based modem. The problem is that since this piece of software
contains most of the code to run the modem, the chipset makers do not give
out the information needed to support these modems, as they would be giving
away most of their design information.

During testing it has been shown that some software-based modems
require almost 33% of a P5/133 CPU to run reliably, so I usually recommend
staying-away from these devices.
