Define a listener for TN3270 terminals to invoke the transaction on your Enterprise Server region: 
               	 
            
 
            	 
            
               -  
                  		  In the table of servers on the 
                     			 Home page of Enterprise Server Administration, click 
                     			 Details in the Communications Processes cell that corresponds to the server to which you want to add the listener.

                     			 Add in the Listeners column for the communications process to which you want to add the listener. 
                     		   
                  		
               
-  
                  		  In the 
                     			 Name field, specify a suitable name - e.g. 
                     			 tn3270. 
                     		   
                  		
               
-  
                  		  Allow 
                     			 Endpoint Protocol to default to TCP. 
                     		   
                  		
               
-  
                  		  In 
                     			 Endpoint Address, set the port number for the listener to 
                     			 *.nnnn where 
                     			 nnnn is a port number. You can use any number above 5000 that isn't already in use.

                  		  In the 
                     			 Supported Conversation Type group, click 
                     			 TN3270.
