Virtual Communications Port (COM4) Driver

The Virtual Communications Port (COM4) driver enables Windows to recognize Recursion’s USB virtual communications port and make it available to software that uses serial connections.

• Application connectivity: Allows serial communication software to access the device using its assigned port, shown as COM4 in this device listing.
• Device recognition: Helps Windows identify and configure the virtual communications port when the correct driver package is installed.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows release and system architecture.

How to Install Virtual Communications Port (COM4) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the device’s hardware IDs if you need to verify that the package matches your Recursion hardware.
2. Choose a compatible package. Before starting your Virtual Communications Port (COM4) driver download for Windows, review the package’s compatibility information. If a free download is offered, confirm its source and select the latest version suitable for your system.
3. Extract and install the driver. Unzip the downloaded archive if necessary. Run the included installer, or open Device Manager, right-click the device, choose the driver update option, and browse to the extracted driver folder.
4. Reconnect and verify. Restart Windows if prompted, then reconnect the USB device. Look under “Ports (COM & LPT)” in Device Manager and check for warning icons. Windows may assign a port number other than COM4.
5. Configure your application. Select the port number displayed in Device Manager and use the communication settings required by your hardware. For Windows 10/11 setups, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.

Keep the driver updated when a compatible release addresses a problem or supports a system change. Before you update, review any available release notes and retain the working installer so you can restore your previous setup if needed.
