The Novatel Wireless Expedite EV-DO Status Port Windows Driver is a driver for a specific piece of hardware from Novatel Wireless, typically used in conjunction with EV-DO (Evolution Data Optimized) wireless modems, which provide mobile broadband access over cellular networks. The Status Port refers to a virtual COM (serial) port on the device used for communication between the modem and the computer. This port allows software to monitor and manage the connection status, signal strength, and other parameters of the modem.

When you install the Status Port driver, it enables Windows to recognize and interact with the Novatel EV-DO modem, providing functionality such as checking connection status, sending commands, or even managing device settings through a serial interface.
