Intel Active Management Technology SOL (COM3) Driver

The Intel Active Management Technology SOL (COM3) driver lets Windows recognize the Serial over LAN interface used by Intel AMT on compatible business computers. It is intended for users and IT administrators who need this management interface detected correctly, especially after reinstalling Windows or finding a missing SOL device in Device Manager. Remote serial-console access also requires supported hardware and properly configured Intel AMT; installing the driver alone does not enable remote management.

Key Features

• Identifies the Intel AMT Serial over LAN interface in Device Manager, where it may appear as Intel Active Management Technology SOL (COM3).
• Provides the Windows-side driver component for the SOL interface on supported Intel management platforms.
• Helps resolve missing-driver warnings when the correct package matches your computer’s hardware and operating system.
• Supports deployment alongside compatible Intel Management Engine components, depending on how your computer manufacturer packages its drivers.

How to Install Intel Active Management Technology SOL (COM3) Driver

1. Check your computer and Windows version. Note your PC model and whether Windows is 32-bit or 64-bit. Packages may be available for Windows 11, 10, 8, or 7, but support varies by system generation. For Windows 10/11, confirm compatibility with your specific model rather than assuming an older package will work.
2. Choose the matching package. Before starting an Intel Active Management Technology SOL (COM3) driver download for Windows, compare the supported hardware and operating systems with your PC. Select the latest version approved for your system, not simply the highest version number.
3. Download and extract the files. Use a trusted manufacturer-provided package for a free download. If the archive contains several management components, consult its instructions to locate the SOL driver.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the SOL device, choose Update driver, and browse to the extracted driver folder. Follow the prompts and restart if requested.
5. Verify detection. Check Device Manager for the SOL entry and confirm that no warning icon remains. COM3 is a port assignment and can differ between systems; it does not by itself determine driver compatibility.

Keep the driver updated through your computer manufacturer’s supported releases to address documented compatibility issues and fixes. Before you update a working installation, review the release notes and confirm that the package applies to your hardware and Windows version.

Common Issues and Fixes

• Install fails or shows Code 10/28: The SOL driver depends on the Intel Management Engine Interface (MEI) driver. Install the matching MEI/chipset driver first, reboot, then update the SOL driver; avoid mixing packages from different Intel AMT generations.
• Device not detected / no COM3: Confirm AMT is enabled in BIOS/firmware and SOL/Serial Over LAN is enabled in the ME configuration. Check Device Manager for an unknown PCI serial device; if missing, reinstall MEI and rescan hardware.
• COM port missing or busy: If COM3 is already assigned or in use, change the SOL port to another free COM number in Device Manager > Ports > Properties > Port Settings > Advanced, then restart the AMT SOL service/application using it.
