ZTE EXT AT Interface (COM14) Driver

The ZTE EXT AT Interface (COM14) driver allows Windows to recognize the USB-connected ZTE device’s extended AT-command interface as a serial communication port. It is intended for users whose compatible ZTE modem or mobile broadband device shows an unrecognized interface, a missing driver warning, or a communication problem in Device Manager.

Key Features

• USB-to-serial communication: Provides access to the device’s AT-command interface, which compatible software can use for supported status queries, configuration tasks, and diagnostics.
• Device recognition: Helps Windows identify the interface correctly instead of listing it as an unknown USB device.
• COM-port access: Enables applications that require a serial port to communicate with the interface. COM14 is the assigned port number on this system; another computer may assign a different number.
• Support for listed Windows systems: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the specific driver package and whether your installation is 32-bit or 64-bit.

How to Install ZTE EXT AT Interface (COM14) Driver

1. Check the device and operating system. Open Device Manager and locate the ZTE interface, usually under Ports (COM & LPT) or Other devices. Review its hardware IDs under Properties > Details to help confirm the correct package.
2. Choose a matching package. Before starting your ZTE EXT AT Interface (COM14) driver download for Windows, verify the supported hardware IDs, Windows edition, and system architecture. Select the latest version that explicitly supports your device.
3. Download and extract the files. Use a trusted free download source, preferably the manufacturer or your device supplier. Extract compressed files to an accessible folder, and avoid packages that require unrelated software.
4. Install the driver. Run the included setup program if available. Alternatively, right-click the interface in Device Manager, select Update driver, choose the option to browse your computer, and point Windows to the extracted folder.
5. Verify the connection. Restart if prompted, reconnect the device, and check that the interface appears without a warning icon. Select its current COM-port number in your compatible application.

Keep the driver updated when a compatible release addresses connection issues or improves reliability. For Windows 10/11 systems, check compatibility separately: Windows 10 is listed here, but Windows 11 support is not confirmed. Before an update, retain a working driver package so you can revert if necessary.
