虚拟串口 5.4

Virtual Serial Port by Zhengzhou Jiechen Electronic Technology Co., Ltd. is a utility that lets you create and manage software-based COM ports, enabling serial communication without dedicated hardware. It emulates null-modem connections so two applications can exchange data as if they were linked by a physical cable. The tool is ideal for developers, testers, and system integrators who work with serial protocols and legacy applications.

Key capabilities:

• Create one or more virtual COM ports and pair them for data exchange
• Bridge data between virtual and physical serial ports to support legacy software and devices
• Configure standard serial parameters (baud rate, data bits, parity, stop bits, and flow control)
• Monitor and log serial traffic for diagnostics and troubleshooting
• Save and restore port configurations to keep setups consistent across sessions
• Clean, intuitive interface for quick setup and operation

Typical uses:

• Testing serial-based applications without requiring hardware on hand
• Replacing null-modem cables in labs, demos, or automated test rigs
• Connecting legacy COM-port software to modern systems
• Simulating serial devices and validating protocol behavior

Developed by Zhengzhou Jiechen Electronic Technology Co., Ltd., Virtual Serial Port streamlines serial workflows, reduces setup time, and helps you deliver reliable results when working with COM-port communications.
