J6 All received signals must be at
V.24 signal level.
All received signals can be in the
positive voltage region.
With the submodule 0AA23, bridge 6 has no function; all signals can lie in
the positive range (corresponds to bridge setting 2-3).
With jumper J9, CTS can be set permanently to quiescent potential, i.e.
switched through from the front connector.
