Was able to mess around a little with the KPC-3+ at lunch. I need to take a look at my COM 1 settings.
8 data bits
1 stop bit
hardware flow control
There should also be a parameter to adjust the port on the KPC-3+ that connects to the PCs COM 1.
… yes there is… ABAUD. Default is 0, which does a self check. I need to set ABAUD to 9600.
