ZTE CMCC AT Interface (COM61) Driver

The ZTE CMCC AT Interface (COM61) driver helps Windows recognize the AT-command interface exposed by compatible ZTE USB devices, allowing supported software to communicate with the device through a virtual serial port. You may need it if Device Manager shows an unidentified interface, a warning icon, or a missing COM port after connecting your ZTE hardware.

Key Features

• Enables AT-command communication between compatible ZTE hardware and applications used for device configuration, diagnostics, or modem management.
• Provides the serial-port interface needed for software that communicates through a COM port. COM61 is the port assignment shown on this system; Windows may assign a different number after installation.
• Supports compatible driver packages for Windows 10, 8.1, 7, Vista, and XP, subject to the package’s operating-system and architecture requirements.
• Helps resolve recognition problems caused by a missing or incorrectly matched driver, so compatible applications can access the interface.

How to Install ZTE CMCC AT Interface (COM61) Driver

1. Check your device and Windows version. In Device Manager, locate the ZTE interface and open Properties to review its hardware IDs. Confirm whether your Windows installation is 32-bit or 64-bit before choosing a package.
2. Select a matching package. Before starting your ZTE CMCC AT Interface (COM61) driver download for Windows, verify that the listed hardware IDs and operating system match your computer. Choose the latest version that explicitly supports your device, rather than assuming every newer release is compatible.
3. Download and extract the files. If using a free download, confirm that it comes from a trusted source and contains the expected driver files. Extract compressed archives before proceeding.
4. Install the driver. Run the included installer if available, or right-click the interface in Device Manager, select Update driver, and browse to the extracted folder. Follow the prompts; avoid bypassing driver-signature warnings for an unverified package.
5. Reconnect and test. Restart if prompted, reconnect the device, and check Device Manager for a working COM-port entry without warning icons. Select the assigned port in your application.

Keep the driver updated when a compatible release addresses connection problems or improves reliability. For Windows 10/11 systems, check compatibility separately: Windows 10 is listed as supported, but Windows 11 support is not confirmed here. Only update with a package matched to your hardware and operating system.
