Did anyone ever solve this? I have the EXACT same thing. I have an Envoy and Virtual VP with COM0COM on Windows 7 64 bit. Weatherlink, VirtualVP, and Cumulus all work with this combo, but VWS will NOT. If I don't run VVP, and run VWS and set it to COM 3, Windows COM port assigned to the Envoy, it works fine. It just won't work thru the VVP/COM0COM virtual ports.
I read this entire thread and it just stopped with no apparent solution. My Envoy is pretty new, so likely has the latest firmware. I have a VP2 console on another computer running this same software combo and VWS works fine, so it HAS to be the Envoy and VWS communicating thru the virtual serial port, but I don't know how to solve it. I tried the TCP/IP thing and that didn't work either.
Anyone know if this has been made to work?
