The ZTE AT Port Windows driver is typically related to ZTE mobile devices or modems, particularly USB modems or mobile hotspots. The "AT Port" refers to the AT command interface, which is a standard way for modems and mobile broadband devices to communicate with a computer. The AT (Attention) commands are used to control modem functions such as sending text messages, making calls, or connecting to the internet. This interface allows the computer to interact with the mobile device through the serial port or virtual COM port.

When you see a "ZTE AT Port" in Device Manager on Windows, it often indicates that the computer is detecting a ZTE mobile device or USB modem but doesn't yet have the appropriate driver installed to fully support communication with the device.
