The AC97 SoftV92 Data Fax Modem driver is designed for a V.92 modem that supports both data and fax functionality. The AC97 refers to the Audio Codec '97 standard, which is primarily for audio chips, but it can also handle modems integrated with certain chipsets. The SoftV92 part indicates that the modem uses software-based processing (also known as a "soft" modem), meaning part of the modem's processing is done by the computer's CPU rather than dedicated hardware.

This modem was commonly used in older PCs, allowing for dial-up internet connections and fax capabilities, especially when broadband was not widely available.
