[Elecraft] setting power via RS232 with KPA100

I would suggest this is a nature-of-beast issue.

One must leave RIT knob centered, otherwise clearing it by
remote control results in RIT going back to where knob is
pointing (I drive RIT up & down by remote).

Makes sense when you think about how the knobs are read.
No idea if the reaction is immediate on return to receive (didn't
bother to check), but display changes on next update.
