[Elecraft] KAT-500 remote control using serial port

[DAVID INGEBRIGHT]

I have the KAT-500 Utility working fine through the serial cable and USB. Now to get it running over the internet on the RRC 1258. Using the RRC COM 2 Port, the set up wants to know the serial protocol, The stop bits, the data bits and the parity. I see someone asked that back in 2014 but can't seem to find the answer. Cannot find this info in the KAT500 manual.
