HHD Software Virtual Serial Port Tools 7.0

HHD Software Virtual Serial Port Tools by HHD Software, Ltd. is a Windows utility for creating and managing software-based COM ports that emulate real serial hardware. It enables you to set up virtual null‑modem pairs so two applications can exchange data as if connected by a physical cable—no extra devices required. Ideal for developers, testers, and integrators, it streamlines building, debugging, and automating serial communication workflows.

Key benefits:

• Create and remove virtual COM port pairs in seconds
• Connect existing applications via the standard Windows serial API, typically without code changes
• Configure familiar serial parameters (baud rate, parity, data/stop bits, flow control)
• Simulate devices and reproducible test scenarios to validate protocols and reproduce issues
• Complement monitoring and analysis with HHD Software’s other serial tools for end‑to‑end diagnostics

Whether you’re validating a serial client/server, simulating equipment, or running automated tests, Virtual Serial Port Tools helps you work faster and more reliably—without relying on physical COM hardware.
