ZTE AT Interface (COM13) Driver

The ZTE AT Interface (COM13) driver allows Windows to communicate with the AT-command interface exposed by a compatible ZTE USB device. It is intended for users whose ZTE modem or other supported device appears as an unrecognized interface, has a warning icon in Device Manager, or cannot communicate with software that uses its serial connection.

Key Features

• AT-command communication: Provides access to a serial interface that compatible applications can use to send supported commands and read device responses.
• USB interface recognition: Helps Windows identify the ZTE AT interface as a COM port rather than an unknown USB device.
• Serial application support: Enables compatible modem utilities, diagnostic tools, and terminal applications to communicate through the assigned port.
• Windows compatibility: Intended for Windows 10, 8.1, 7, Vista, and XP when the package matches your device and system architecture. The COM13 label is a port assignment; Windows may assign a different number after installation.

How to Install ZTE AT Interface (COM13) Driver

1. Check your device and Windows edition. Open Device Manager, locate the ZTE interface, and review its hardware IDs under Properties > Details. Confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a matching package. Before starting your ZTE AT Interface (COM13) driver download for Windows, verify the supported hardware IDs and operating systems. Choose a free download from a trusted source, preferably the manufacturer, and check that the latest version offered actually supports your device.
3. Extract and install the driver. If the package includes a setup program, follow its instructions. Otherwise, extract the files, right-click the interface in Device Manager, select Update driver, and browse to the extracted folder.
4. Reconnect the device if needed. Complete any restart requested by the installer, then reconnect the ZTE device. Avoid disabling driver-signature checks to force an incompatible package.
5. Verify the connection. Check that the interface appears without a warning icon and select its assigned COM port in your application. For Windows 10/11 systems, verify compatibility separately: Windows 10 is listed here, but Windows 11 support is not confirmed.

Keep the driver updated when a compatible update addresses connection issues or improves support for your Windows installation. If your current setup works reliably, review compatibility information before replacing it, and retain the previous package in case you need to roll back.
