Zach,
PCMCIA modems are bears to use under DOS. First, you need an "enabler," which
isn't hard to find. Then you need a "socket" driver.
I, too, have a notebook with an unworking PCMCIA card modem. I have searched
the internet and all the web sites of PCMCIA modem manufacturers and have not
found a "socket" driver that will work with my card. I actually had to track
down the manufacturer of the card using the FCC number on it. One type of
PCMCIA card (CARDsomething) will only work with socket drivers from the
company that makes the card.
The greatest amount of information on PCMCIA cards that I found was at
Phoenix Technologies web site (www.phoenixtech.com ???). Right, the same
company known for making BIOSes for DOS computers.
Hope this helps.
