The Conexant HCF V90 Data Fax Voice USB Modem is a USB modem that provides dial-up internet access, faxing, and voice functionalities, typically used in environments where broadband internet is not available or for legacy systems that require dial-up connectivity. The "V90" part refers to the 56Kbps V.90 standard, which was a widely used protocol for dial-up modems that allows up to 56 kilobits per second data transmission.
The Conexant HCF V90 modem was a popular choice for consumer PCs in the late 1990s and early 2000s, although it is now largely obsolete in favor of broadband technologies like DSL and cable internet. Despite its age, some users may still need this driver for legacy systems or specific use cases.
