Virtual Serial Port Driver PRO

We started using it to troubleshoot communication between two Windows applications. Creating a pair of connected COM ports took only a few minutes, and we could immediately start sending data between them. It’s made debugging much more convenient, especially when testing changes without access to the actual hardware.

Excellent program! Clear and clean interface… perfectly “readable”! I use the virtual COM ports of my transceivers (IC7300-IC9700-IC705) for splitting in interface programs that require two independent ports! I use it to PAIR the output of my SDR receiver, when sending audio and CAT, to the interface for FT8 decoding: it doesn’t miss a beat and is PERFECT, unlike another program I used before that was really unreliable! Congratulations! Luca IW3FQT

PS: sorry for my english!

VSPD Pro completely solved a major technical roadblock for us. Our custom .NET application needed to communicate with a hardware device through a COM port, but another essential third-party application already locked that port. With Windows only allowing one application per COM port, we were stuck — until we used VSPD Pro’s Split COM Port feature. It lets us create multiple virtual copies of the physical port, seamlessly feeding the same data stream to both applications in real time. The setup was quick, the performance was stable, and there was zero data loss. VSPD saved us weeks of development time and eliminated the need for costly hardware changes. Truly a reliable, hassle-free solution!

Virtual Serial Port Driver PRO is the go-to solution for handling advanced serial communication tasks. I used it to create custom serial port pairs and monitor data flows in a project that involved integrating several devices with proprietary protocols. The PRO version’s ability to emulate advanced configurations and analyze traffic in real time made troubleshooting seamless. A must-have for anyone working with multi-device serial environments.

Virtual Serial Port Driver PRO has been an essential tool in our robotics lab. We used it to simulate multiple serial connections between our control software and robot modules. The ability to create complex serial port bundles and split data streams was incredibly useful for testing communication reliability. Its advanced features saved us significant time during development and debugging. Highly recommended for professionals working with intricate serial setups.
