property Port;
Description
Port is an Integer property that identifies the port number on the local system where data is sent and received.

Note: Many port numbers are associated, by convention, with a particular service such as ftp or http as described in IdPorts. Some protocols use pre-defined port numbers. Port numbers below 1024 are reserved, but using a number above 1024 does not guarantee there will be no conflict.
