you set up VVP to use a virtual com port (paired) that the software connects to
that is how VVP was originaly setup to work before TCP/IP support was added
I tried to get this type of set up to work without success. My data logger is on comport 6 which screwed up things as the virtual driver uses com 6. I'm guessing i need to change my data logger com to something different. I lost connection between VVP and the logger during my trials so returned to my old set up using tcp/ip. I might install the virtual drivers again and give it another try.
