locked WSJTX and PowerSDR not communicating #Cat_RigControl




I’ve previously had an earlier version of WSJT running with Power SDR on a Windows 7 PC. I am trying to get the latest version (2.3.1) running but I keep getting this message -  below. I’m using ComOCom for CAT control which implements COM3 and COM4.


I cannot find that Hamlib is a program running. I really am stuck. Any ideas please.


Hamlib error: IO error

serial_open: Unable to open COM3 - No error

serial.c(237):serial_open return(-6)

rig.c(758):rig_open return(-6) while opening connection to rig
