      If pin 2 is open on the DE-9, that would prevent you from receiving
      any data from port A. Pin 1 is of course port B out, and pin 3 is +5V
      out for a GPS receiver.

      Scott should answer that one, but on a new unit, it would think it would be
      better to send it back unless you could see an easy fix.
