Thanks for the feedback.  I hope that someone else can continue this
work now that I've identified the problem and have developed a solution
that works for my needs with no obvious side-effects.

Given that this is such base functionality, I'm surprised that no one
else has mentioned anything up to this point; I guess no one else
attempts to change the baud rate for subsequent reboots?  (Rhetorical,
no need to answer.)

All the best with the upcoming release,
