Pericom Serial Port Device (COM3) Driver

The Pericom Serial Port Device (COM3) driver allows Windows to recognize the device and communicate with connected serial equipment through its assigned COM port. You may need it when setting up the device for the first time, reinstalling Windows, or troubleshooting a missing COM3 port or a driver warning in Device Manager.

Key Features

• Enables serial communication: Provides the driver support Windows needs to exchange data with equipment connected through the Pericom serial interface.
• Supports COM-port access: Makes the serial port available to compatible applications, such as terminal software and equipment configuration utilities.
• Covers older Windows systems: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for your Windows version and 32-bit or 64-bit architecture.
• Helps restore device recognition: Installing a matching driver can resolve recognition problems caused by missing or incompatible driver files.

How to Install Pericom Serial Port Device (COM3) Driver

1. Check your system and device. Confirm your Windows version and architecture. In Device Manager, open the device’s Properties and check Details > Hardware Ids to help identify a matching package.
2. Choose a compatible download. Before selecting a Pericom Serial Port Device (COM3) driver download for Windows, verify the supported operating systems and hardware IDs. Choose the latest version that explicitly supports your device and system. For Windows 10/11 searches, note that Windows 11 support is not confirmed by the supplied compatibility list.
3. Download and extract the files. Use a trusted source, and check that any free download offer contains the actual driver package rather than an unrelated installer. Extract compressed files before proceeding.
4. Install the driver. Run the supplied setup program if available. Alternatively, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Older Windows versions may use slightly different menu labels.
5. Verify operation. Restart if prompted, then check that the device appears without a warning icon. Confirm the assigned COM port and select that same port in your serial application; Windows may assign a number other than COM3.

Keep the driver updated when a compatible release addresses a problem you encounter or improves support for your system. Before an update, review the package notes and retain your working installer so you can restore the previous driver if necessary.
