Virtual Serial 7.2

Virtual Serial by FabulaTech is a Windows utility that creates fully functional virtual COM ports for software testing, integration, and device simulation—no physical serial hardware required. It lets you build pairs of ports linked by a virtual null‑modem connection, so data written to one port instantly appears on its counterpart. This is ideal for connecting two serial applications, replacing loopback cables, or emulating devices during development and QA.

Key features:

• Create multiple virtual COM port pairs
• Full emulation of serial settings and signals (baud rate, data bits, parity, stop bits, flow control; DTR/DSR, RTS/CTS, DCD, RI)
• Fast, reliable, driver‑level data exchange with low latency
• Persistent port configuration with auto‑creation at startup
• Easy management via a straightforward UI; automation available through FabulaTech’s optional SDKs
• Broad compatibility with legacy and modern serial applications on 32/64‑bit Windows

Typical use cases:

• Debugging and QA for serial‑based software
• Bridging two applications that communicate over COM
• Simulating serial hardware for demos or CI pipelines
• Replacing physical null‑modem cables and loopback plugs

With Virtual Serial, you can streamline development workflows, reduce hardware dependencies, and ensure consistent, reproducible serial communication scenarios.
