Latest Driver for this PC Card modem. Find your modem via the sticker(s) on the bottom of the PCMCIA card. Phoebe Micro only supports and has written drivers for Win 95/98 for this card. If you need DOS/Win3.1/NT 4/ME/2000 drivers, pray that the OS has them! This card uses a standard Cirrus Logic chipset, so you shouldn't have much trouble. Linux/UNIX users should just try the Cirrus PCMCIA modem drivers, they have worked OK for me in the past.
