This option allows you relocate the Lyris Command Protocol Port number. By default, Lyris uses port 2020 as its LCP port. This is how the Lyris Web Interface communicates with the
Lyris server. You would only change this port number if you had a TCP/IP port conflict with another service.
If you change the LCP Port number, you will also need to change the server port setting in your Lyris Web Interface's lyris.plc file. See TCP/IP Port of Lyris Server.
