The Conexant HSFi V9x MiniPCI Modem is a type of hardware modem used in laptops or computers, typically older systems, to provide dial-up internet access through a telephone line. This modem uses the Conexant HSFi (High-Speed Fax Interface) chipset, which is a low-cost solution for providing modem functionality. The modem itself is integrated onto the motherboard (in the case of laptops) or installed as a MiniPCI card in desktops.
