Bruce, if what you said is right then I'm not understanding what you
mean by serial.  Tx and Rx are usually the serial lines with a reference
to a gnd.  If they are tied together with something then what is it? I
typically tie Tx and Rx together and use that line with ground for
communications.  If your saying tie these with something else then I
don't know what it is unless you are referencing the driver enables?
