              Specify the port number used by the socket TCTI. The default is 2321.

       ENVIRONMENT: TCTI
              This collection of environment variables that may be used to configure  the  varous
              TCTI  modules  available.   The  values  passed  through  these  variables  can  be
              overridden on a per-command basis using the available command line options.
