Unimodem Full-Duplex Audio Device Driver
Unimodem Half-Duplex Audio Device Driver
1.000 (1999-07-15) via .inf
This is the Win2K Drivers. Can be used under XP. Does not provide perfect functionality but does allow the modem to be used. Have found the need to turn off "Wait for Dial-tone" option of the modem due to dial-tone never being found. Recommend driver updated to XP driver when this is released.
