With this stuff you can you your one HW port with many apps at the same time. Like your TRX sync ant same time with log, api, and so on. In my own case i use it for my Kenwood TS-590SG and Yaesu FT-897D with WSJT-X, Log4OM, SDRuno/SDR console , ARCP-590G. After setup of VSPE you need save config ant move it to windows startup folder, ant in all software to set virtual port! Like in my case COM10 for Kenwood TS-590SG and COM8 for Yaesu FT-897d.
