MosChip High Speed PCI Serial Port Driver

The MosChip High Speed PCI Serial Port driver enables Windows to recognize and communicate with the serial ports on a compatible MosChip PCI expansion card. It connects the card’s hardware to applications that use COM ports, helping you work with compatible serial equipment such as modems, industrial controllers, and older peripherals.

Key Features

• COM port access: Allows serial communication software to locate and use supported ports on your MosChip expansion card.
• Serial connection settings: Supports configuration of available communication parameters, such as baud rate, parity, data bits, and stop bits, through Windows or your application.
• Windows device management: Helps Windows identify the serial-port hardware so you can check its status and manage the installed driver in Device Manager.
• Support for legacy equipment: Provides the software interface needed to connect compatible serial devices to a PC with an appropriate PCI slot.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and locate the MosChip serial controller. An unconfigured card may appear under Other devices. Check its Hardware IDs in Properties, and confirm whether your PC runs Windows 11, 10, 8, or 7, including the system architecture.

1. Choose a matching driver package. Download the MosChip High Speed PCI Serial Port driver that explicitly supports your hardware ID and Windows version. Packages can differ between card models, so do not assume that every MosChip serial driver is interchangeable.

1. Extract and install the driver. If the download is compressed, extract it first. Run the included installer if one is provided. Otherwise, right-click the device in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Restart if requested. Follow the installer’s instructions, then check Device Manager. A successfully configured port should normally appear under Ports (COM & LPT) without a warning icon.

1. Configure and test the connection. Note the assigned COM number and select it in your serial application. Match the communication settings to the connected equipment, then test data transfer using a suitable cable.

For Windows 11 or any other listed version, verify compatibility in the package documentation before installing. If Windows rejects the driver, look for a compatible signed package rather than disabling driver-signature checks.
