The AC97 Data Fax SoftModem with SmartCP is a software modem that is used for dial-up internet connections, faxing, and other telecommunications tasks. It was commonly used in older computers before broadband internet became widespread. This modem uses the AC97 audio standard (originally developed for audio) for data transfer, and the SmartCP feature enhances its performance and reliability.

The Windows driver for the AC97 Data Fax SoftModem allows the modem to communicate with the operating system and function correctly, enabling faxing and dial-up networking capabilities.
