The AC97 Soft Data Fax Modem with SmartCP is a software modem that was commonly used in computers for dial-up internet connections and fax capabilities. It is a part of the AC97 audio codec standard, which was typically used in older PCs for audio and modem functionality.

Here's a breakdown of the components:

• AC97: This is a standard for audio and modem communication, primarily used in the late 1990s and early 2000s. It typically refers to an integrated audio and modem chip on a motherboard or a sound card.
• Soft Data Fax Modem: This refers to a software-based modem. Unlike hardware modems, which have dedicated hardware for processing data and fax signals, soft modems rely on the computer's CPU to process the data.
• SmartCP: SmartCP is a proprietary technology developed by Conexant, a semiconductor company, to improve the performance of soft modems. It allows the modem to work more efficiently with fewer system resources.
