HRD's rig control component was very poorly written. I gave Rick and
other involved persons specific documentation of HRD sending the same
command multiple times less than 1 msec apart as well as serial logs
showing continuous serial transmission even when the polling rate was
set longer than 500 msec.
I have not had time to evaluate the 5.1 "fixes" but I suspect Rick will
need to do a nearly complete rewrite of the serial port/CAT controls if
the problems are to be fixed.
