Prolific USB-to-Serial Comm Port (COM6) Driver

The Prolific USB-to-Serial Comm Port (COM6) driver enables Windows to communicate with compatible serial equipment through a Prolific-based USB-to-serial adapter. It is useful for connecting devices such as industrial controllers, GPS receivers, diagnostic tools, and older peripherals that require a serial connection rather than a standard USB interface.

Key Features

• USB-to-serial communication: Allows compatible applications to exchange data with serial hardware connected through your adapter.
• COM port access: Makes the adapter available as a Windows communication port. COM6 is the assigned port number, which may change when the adapter is reconnected or system settings are adjusted.
• Configurable serial settings: Supports settings such as baud rate, parity, and flow control, subject to the adapter and connected equipment’s capabilities.
• Windows compatibility options: Driver packages are available for supported Prolific hardware on Windows 10, 8.1, 7, Vista, and XP; the correct package depends on the chipset and operating system.

How to Install Prolific USB-to-Serial Comm Port (COM6) Driver

1. Identify your adapter and Windows version. Open Device Manager and check the adapter’s properties, including its hardware IDs if needed. Confirm whether Windows is 32-bit or 64-bit. For Windows 10/11 systems, verify chipset-specific support: Windows 11 is not included in this device’s listed supported operating systems.
2. Choose a compatible package. Before starting your Prolific USB-to-Serial Comm Port (COM6) driver download for Windows, check the package’s supported chipsets and operating systems. Select a trusted free download from Prolific or your adapter manufacturer rather than assuming the latest version supports every older adapter.
3. Install the driver. Follow the package instructions, disconnecting the adapter if directed. Run the installer, or use Device Manager’s Update driver option to browse to the extracted driver files.
4. Reconnect and verify detection. Restart Windows if prompted, then connect the adapter. In Device Manager, expand Ports (COM & LPT) and confirm that the device appears without a warning symbol.
5. Configure your application. Select the assigned COM port and match the serial settings required by your equipment. If Windows assigns a port other than COM6, use that number in your software.

Keep the driver updated when a compatible release addresses connection problems or improves support for your system. Before an update, check the release notes and hardware requirements; older Prolific chipsets may need a legacy driver rather than the newest package.
