property Port: Integer read FPort write SetPort;
ID number that identifies the server socket connection.
The value of Port is usually associated with the service the client wishes to use on the server application.
Port numbers allow a single system, identified by the Host or Address property, to host multiple connections simultaneously. Many values of Port are associated by convention with a particular service such as ftp or http.
- Note: Trying to change Port when the connection is open raises an ESocketError exception.
