I can't say that it would cross my mind to look for my missing printf output
on a serial port, even if I was using a serial port in other parts of the
program to talk to something.  Whatever it was that gave you the hunch to do
that is probably at the core of your problem.

Well, no, not really, since you've given very few details to go on.  I'd
SWAG that you've somewhere, somehow, redirected stdout to the serial port
you're trying to talk to those devices on.
