No, you do not need to loop back any signals. DEC didn't like to abuse modem
control for flow control.
What about the connections between the TTL signals and the line
drivers/receivers? There are definitley such connections to be made in the
Berg connector (like TTL SERIAL DATA IN on connector pin E). For EIA you
need to connect pin E with pin M. (See also page 178 in the microcomputer
interfaces handbook [1980]).
