       -p, --socket-port
              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.
