The PCI SoftV92 Data Fax Modem driver is software that allows your computer to communicate with a PCI-based modem that supports V.92 standards for data and fax transmissions over telephone lines. The V.92 standard enables faster modem connections, faster upload speeds, and the ability to use the modem for both data and fax functions simultaneously. The driver ensures that the modem is properly recognized by Windows and that you can use it for tasks such as sending faxes or connecting to the internet via dial-up.
