The Communications Port (COM29) driver lets Windows communicate with the serial interface assigned to COM29, allowing compatible applications to exchange data with connected equipment. You may need to install or update it if the port shows a warning in Device Manager, disappears, or fails to work with your serial tools. Although this device is listed under Microsoft in the USB category, COM29 is a port assignment—not a unique hardware model—so the correct driver depends on the underlying controller or USB-to-serial adapter.
Key Features
- Serial communication support: Provides the interface Windows applications use to send and receive data through the assigned COM port.
- Device Manager integration: Lets you check device status, view driver information, and adjust supported port settings.
- Configurable connection settings: Supports serial parameters such as baud rate, parity, and flow control where the hardware and driver allow them.
- Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; individual driver packages may support only some of these versions.
How to Install Communications Port (COM29) Driver
- Identify the hardware. Open Device Manager and locate Communications Port (COM29), usually under Ports (COM & LPT). Open Properties > Details > Hardware Ids to identify the controller or adapter.
- Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. If searching for Windows 10/11 support, verify compatibility explicitly: Windows 11 is not included in this device listing.
- Choose a matching package. Before selecting a Communications Port (COM29) driver download for Windows, compare its supported hardware IDs and operating systems with your device. Use Windows Update or the hardware manufacturer’s official support resources for a free download when available.
- Install the driver. Run the official installer, or select Update driver in Device Manager and browse to the extracted driver folder. Follow the prompts and restart if requested.
- Test the connection. Confirm that the device has no warning icon, then select COM29 in your application. Match the connection settings to the attached equipment’s requirements.
Keep the driver updated through trusted sources, especially when troubleshooting connection problems. The latest version is useful only if it supports your specific hardware and Windows edition; a higher version number alone does not guarantee a better match. If an update causes problems, use Device Manager’s Roll Back Driver option when available.
