The Conexant Data Fax Modem with SmartCP is a software driver package that supports Conexant's hardware-based modems, specifically those used for dial-up internet access, faxing, and other telecommunications functions. "SmartCP" (Smart Communication Platform) is part of Conexant's technology designed to enhance modem performance, including features like noise reduction, speed optimization, and better signal handling.

These modems were commonly found in older PCs or laptops that still used dial-up connections or fax capabilities, often before broadband became widespread.
