This method sets the remote TCP port that the RNI at the other end of the
connection uses to receive connections from the LNS Server. For a downlink
session, it is the responsibility of the xDriver lookup extension to map the
downlink lookup key to the database, extract the remote TCP port from the
database, and fill it into the SCO using this method.
