Drew,
If you're talking about a dial-up modem, then a fully hardware based
(on-board controller and DSP chips) don't need drivers. You just plug it
in
and windows, including Vista, will install everything you need to make it
work properly. One of the best fully hardware based modems is the U.S
Robotics Performance Pro. It costs full retail about $70, or so,
depending
what kind of deal you find. These type modems cost more because they are
worth more.
Don't be fooled by a partially configured hardware modem. Some
manufacturers include the DSP (Digital Signal Processor) on board, but
perform the controller function by software. They will market this type
modem as a hardware modem. However, now you need software compatible with
the operating system, because the controller function is performed by
software. These type name brand modems typically sell for from $20-$30,
give
or take a few.
If you need a FAX, Windows includes a FAX function. Just install it and
you
don't have to worry about finding a Vista compatible FAX.
You can find software based modems, which are modems where both the
controller and the DSP functions are performed by software. Now you
really
need something that is Vista Compatible. These modems are referred to as
"Soft" modems. They are little more than a device to enable a connection
to
be made between the telephone line and the computer. Everything else is
done
by software. These sometimes can work very well, but sometimes not. Such
modems can be found for as little as $5-$30, depending on the deal you
find
and the name of the brand. This is probably more than you ever wanted to
know.
