Port (-PORT)
Use the Port adapter command (-PORT or -P) to specify the port number on which the CICS Listener listens. This is customer defined.
This is a required command if -HOST is specified. Do not use the -PORT command if you are using the CICS adapter from within a CICS region.
This command is mutually exclusive with the Service (-SERVICE) command. Either Port or Service must be specified.
-PORT port_number
For example:
-PORT 4321
Where 4321 is the port number where the CICS listener listens. Consult your CICS systems programmer for the port number.
