The Mission Behind com0com.com
Our goal is simple: To ensure that com0com, the world’s most reliable open-source virtual serial port emulator, remains accessible and fully functional on every modern Windows device, despite evolving security standards.
Bridging the Gap (2004 – 2026)
Originally launched on SourceForge by Vyacheslav Frolov, com0com revolutionized how developers test serial communication. However, as Windows evolved with Driver Signature Enforcement and Secure Boot, many users found the original builds impossible to install.
com0com.com was established as a dedicated hub to bridge this gap. We don’t just host files; we monitor Windows kernel updates, test compatibility on the latest builds (including Windows 11 24H2), and provide the verified signature patches necessary for professional industrial and development use.
Project Integrity
- ✔ 100% GPL Open Source Compliance
- ✔ No Adware or Bundled Software
- ✔ Verified Driver Signatures (2026)
- ✔ Community-Driven Technical Support
Why Trust com0com.com?
We operate on four fundamental pillars to support the global serial communication community.
Security First
Every driver patch we distribute undergoes rigorous sandbox testing and multi-engine antivirus scans. We ensure your kernel stays safe.
Total Transparency
We believe in the GPL ethos. We provide clear documentation on how our signatures are applied and maintain full respect for the original source code.
Modern Ready
While the original project slowed down, we keep moving. We focus on Windows 11, ARM64, and Server 2025 compatibility so you don’t have to.
