I think that using an I/O pin that can be sampled would be the best
solution.  Or pick two that a jumper can be placed across - if they're
connected, run with/without the console port.

Another way, but might take some redesign is to use some of the normally
unused pins in the serial connector which can flag the NO-CONSOLE mode.
