ZTE CMCC AT Interface (COM5) Driver

The ZTE CMCC AT Interface (COM5) driver helps Windows recognize the AT-command interface exposed by a compatible ZTE USB device, allowing supported software to communicate with it through a virtual serial port. You may need this driver if Device Manager shows an unrecognized interface, a warning icon, or a missing COM port after connecting your ZTE hardware.

Key Features

• AT-command communication: Enables compatible applications to send modem control and status commands through the device’s serial interface.
• Virtual COM port access: Makes the interface available to software that uses Windows COM ports. Although the device name includes COM5, Windows may assign a different port number.
• USB interface recognition: Helps Windows identify the AT interface correctly rather than leaving it listed as an unknown device.
• Support for older Windows systems: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP. Match the package to your operating system and hardware before installation.

How to Install ZTE CMCC AT Interface (COM5) Driver

1. Confirm the device details. Connect the ZTE device, open Device Manager, and locate the AT interface under Ports (COM & LPT), Other devices, or USB-related entries. Check its Hardware IDs in Properties to help verify the correct package.
2. Choose a compatible package. Before starting your ZTE CMCC AT Interface (COM5) driver download for Windows, confirm that the package supports your hardware and Windows edition, including 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 11 support is not confirmed by the compatibility information provided here.
3. Download and extract the files. Use a trusted source for a free download, and extract the archive if necessary. Avoid packages that require unrelated utilities or ask you to disable security protections.
4. Install the driver. Run the included installer, if available. Alternatively, right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, reconnect the device, and check that the interface appears without a warning icon. Select its assigned COM port in your communication software.

Keep the driver updated when a compatible release addresses connection problems or improves reliability. Check for the latest version that specifically supports your device and operating system; a newer package is not automatically a better match. Before an update, retain a working driver copy or create a restore point so you can recover if needed.
