I've never considered doing this. Except when there's development for 
brand new products, Elecraft firmware typically updates once or twice a 
year. We're seeing a bit more than that now because of the new K3S and 
P3TXMon.

At home, I use real hardware RS232 to control the two K3s looped through 
P3s in my SO2R station. That works with K3 Utility, P3 Utility, N1MM+, 
WSJT-X, and DXLab Commander. The only control lines to my KPA500 and 
KAT500s are PTT via the RCA connectors.

Both the KPA500 and KAT500s are very good at RF-sensing to do their own 
band-switching. I use their USB connections only when I want to load new 
firmware, and I do it by simply moving a USB cable from one unit to 
another. I use the AUX bus only to feed band decoders for switching 
antennas and bandpass filters.

For FD and CQP, I find myself using the USB cables because the computers 
don't have hardware serial ports.
