Unimodem TSP

The Unimodem, or Universal Modem Driver, TSP (Unimdm.tsp) provides access to nearly all standard modems. The versions on Windows 95, Windows 98, and Windows 2000 support voice modems that allow half-duplex streaming. They are supported by the Wave MSP and stream control is possible. Unimodem on Windows NT 4.0 or less does not support voice modems, so direct stream control is not possible .

This TSP supports an address type value of LINEADDRESSTYPE_PHONENUMBER. If the programmer wants to use the dialing rules, the TAPI 3 ITAddressTranslation interface or the TAPI 2 lineTranslateAddress function must be used to obtain a dialable string from a phone number in canonical format.

The Unimodem TSP is installed with Windows NT, Windows 95, Windows 98, and Windows 2000.
