You may well be correct, Zoli.  As I recall, a speed change would
require sending the proper CAT command each time the change is made.
It's possible this could be done in a manner that doesn't mess up the
timing of the sent Morse, I think it would likely be very rig specific.

One thing the K3 and the later models can do is be keyed via the RTS/DTR
line and N1MM+ takes full advantage of that, speed changes and all.
Problem is whether more rigs support that and whether Hamlib supports
it.  Even though I've been a part of the Hamlib project for quite some
time, I'm not sure!  There may be some provision but probably needs some
debugging.  Again, this is a feature that is rig specific.
