      Actually I think TTL may be the default on the T3. That's the one
      annoying difference between the OTUSB and T3 - they have different
      default polarities for the TX line. Try setting it without the TX
      invert bit.

      I think those may have gone out with an older firmware version - the
      production programmer might not have been updated. I'll check on that

      No, afraid you have to do a DUMP ALL.
