[Product Introduction] Virtual Serial Ports Emulator (VSPE) : Virtual Serial Port Emulator

December 21 2025 TEGARA Co., Ltd. engineering, Industrial communication technology, Application development and programming, Overseas Products What's New (Unipos)

Virtual serial port emulator software "Virtual Serial Port Emulator (VSPE)page has been added.

VSPE is a tool for software engineers and developers to create, debug and test applications that use serial ports.You can create various virtual devices for sending and receiving data, and unlike normal serial ports, you can open the same device multiple times with different applications.

VSPE allows multiple applications to share data from physical serial ports, expose serial ports to the local network (via TCP protocol), create device pairs for virtual serial ports, and more.

About License

The Virtual Serial Ports Emulator (VSPE) isPerpetual license.

One license can be used on one computer.However, you can use his VSPE on two computers at the same time under the following conditions.

  • Both computers are owned by the same user “and”
  • Both VSPE applications belong to the same data flow (e.g. connected by TcpServer/TcpClient devices)

 

Try VSPE

By downloading the setup file from the manufacturer's website, it is possible to try VSPE for 4 weeks (after the trial period ends, activation by purchasing a license is required).

Check the "Download latest released version" section:
