I installed the drivers for my keyspan and it says com 4 is ready. When I try to register DHP i keep getting the error "unable to communicate with interface".
Com 4 is the only com that attempts to retrieve cable data. It reads for a few seconds then pops the error.
Maybe one of the settings in the keyspan need changing? When I test the serial port in the keyspan w properties menu it says it passes.
It's funny too because I can see the com port is active while it's trying to register, it's like it times out or something
