The Conexant MiniPCI Modem Enumerator driver is a software component that enables a Conexant modem device (typically a MiniPCI card) to function properly with Windows. The driver allows the operating system to recognize and interact with the modem for tasks like dial-up internet connections or faxing services. The Enumerator part of the name means it helps the system "enumerate" or detect the device when it is installed, allowing Windows to assign appropriate resources and configure it for use.
