isCOBOL ClientListener usage
The isCOBOL ClientListener is activated on the client machine with the following command:
| iscclientd { [-displayport dport] } [-port port]              [-x] | 
•	dport is the port on the client machine that will be used to communicate between the UNIX shell and the ClientListener (by default it’s 10998). 
Note: In order for the -x option to work correctly, any other X11 services must be turned off. Otherwise you may experience unexpected behaviors.
•	port is the port used for connecting to the isCOBOL Server (by default it’s 10999) 
A correct startup will produce an output similar to this:
| Starting client listener on hostname: localhost, on display port: 10998, AS port: 10999 | 
The isCOBOL ClientListener can be launched in the following alternate way to avoid keeping the console busy:
| isclientd { [-displayport dport] } [-port port]             [-x] | 
Once started, the isCOBOL ClientListener is identified by an icon in the system tray.
Right click on the icon to show a pop-up menu with the following options:
•	Info: Display a balloon with the result of the ClientListener startup.
•	About: Display a balloon with version information.
•	Exit: Closes the ClientListener.
