The Conexant SoftK56 Speakerphone PCI Modem is a modem card designed for dial-up internet access and voice communication, often integrated into desktop computers. It combines the functions of a modem and speakerphone, enabling voice calls over the telephone line while also providing dial-up internet access (though dial-up is now largely obsolete due to broadband technologies). The Windows driver for this device allows the operating system to communicate with and manage the modem's functions.
