EVDO Rev A Command Control Port (COM17) Driver

The EVDO Rev A Command Control Port (COM17) driver lets Windows communicate with the command-and-control interface of a Telecom EVDO USB modem. You may need it if the modem’s control port appears as an unknown device, has a warning icon in Device Manager, or is unavailable to compatible modem management software.

Key Features

• Command-port communication: Enables compatible software to send control commands to the modem through its virtual serial interface.
• USB device recognition: Helps Windows identify the modem’s command/control port rather than leaving it listed as an unrecognized USB component.
• Modem management support: Provides the connection used by compatible utilities to access modem settings and status information. Other modem functions may require separate drivers.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, provided the selected package matches your hardware and Windows architecture.

How to Install EVDO Rev A Command Control Port (COM17) Driver

1. Check the device details. Open Device Manager and locate the modem’s control port under Ports (COM & LPT), Other devices, or the relevant USB category. Check its hardware IDs under Properties > Details to confirm the package matches.
2. Choose a compatible package. Before starting an EVDO Rev A Command Control Port (COM17) driver download for Windows, verify the supported operating system and whether you need a 32-bit or 64-bit version. If comparing Windows 10/11 options, note that Windows 11 support is not confirmed here.
3. Download and extract the files. Use a trusted source, and verify compatibility even when the package is offered as a free download. Extract compressed files to an easy-to-find folder.
4. Install the driver. Run the supplied installer, or right-click the device in Device Manager, choose the driver update option, and browse to the extracted folder. Follow the prompts without bypassing security warnings.
5. Confirm operation. Restart if prompted, reconnect the modem, and check that the control port appears without a warning icon. Windows may assign a port number other than COM17; select the assigned port in your modem software.

Keep the driver updated when a compatible release addresses a problem you experience. Check the latest version against your exact modem hardware and operating system before you install an update, and retain a working package in case you need to restore the previous driver.
