ZTE CMCC AT Interface (COM14) Driver

The ZTE CMCC AT Interface (COM14) driver helps Windows recognize the AT-command interface exposed by compatible ZTE USB hardware and make it available as a serial port. It is useful when ZTE connection software or diagnostic tools need to communicate with the device, especially if Device Manager shows an unknown device or a warning beside the interface.

Key Features

• AT-command communication: Enables compatible software to send supported AT commands for device identification, status checks, and configuration.
• USB-to-serial access: Makes the device’s AT interface accessible through a Windows COM port. COM14 is the assigned port number on this system; it may differ on another computer.
• Correct device recognition: Helps Windows identify the interface rather than leaving it listed as an unrecognized USB component.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP, provided the selected package matches your hardware and operating-system architecture.

How to Install ZTE CMCC AT Interface (COM14) Driver

1. Check your system and hardware. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, open the interface’s Properties and check its hardware IDs if you need to verify a package match.
2. Choose a compatible package. Before starting your ZTE CMCC AT Interface (COM14) driver download for Windows, confirm that the package supports your specific ZTE hardware. Select the latest version that explicitly supports your system, rather than assuming any newer package will work.
3. Download and extract the files. Use a trusted source for a free download, scan the downloaded package, and extract it if it arrives as an archive.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the affected interface, choose Update driver, and browse to the extracted driver folder. Follow the prompts; do not bypass driver-signature warnings.
5. Verify the connection. Restart if prompted, reconnect the device, and check that the interface appears without a warning icon. Set your compatible application to the COM port Windows actually assigns.

Keep the driver updated when a compatible release addresses connection problems or software requirements. For Windows 10/11 searches, note that Windows 10 is listed as supported here, but Windows 11 compatibility is not confirmed. Before an update, check the package’s compatibility notes and retain the working installer in case you need to roll back.
