a few questions.
set to mode 3 or mode 4?
the RRC users guide under general Yaesu states set CAT Baud to 38400 so should com 2 be set to 38400 8 ,N. 0? I was using it for previous ft 857 and com 2 settings were different for CAT.
I will be using the serial port on the 991A and HRD for total remote control
