John-

The pin connections you received tell you what to do, but it might help
to have a word description to put meaning to the answer.  The concerned
pins are labelled "Request to Send" and "Clear to Send".  By
criss-crossing the connections, the cable always says, "I'm ready" and
does so in both directions.
