If you want to know whether a specific AppleTalk service is available, you need to find out which AppleTalk services are reachable. To determine the services available to a router, load ATCON and perform a lookup for network entities.
To perform a lookup, follow these steps:
From the Available Actions window, select Lookup Network Entities.
In the Name field, type the name of the service for which you are looking.
To find all services, leave the default value (=). To use a wildcard character, enter the following sequence of keys at the numeric keypad while pressing Alt: 2 , 4 , and 7 .
In the Type field, select the NBP type of the service you want to reach.
Press Enter to get a list of NBP types from which you can select. If the NBP type of the service you want to reach is not in the list, press Insert to insert a new NBP type.
In the Zone field, select the name of the zone in which the remote router resides.
Press Enter to get a list of zones from which you can select.
Select Perform Lookup and press Enter .
The Network Entities Found window appears.
Wait at least 30 seconds for the link to be established and routes to be exchanged, then perform the lookup again. Do not wait for routers to be exchanged for destinations connected by an on-demand link. Also, be aware that performing the lookup for destinations connected by an on-demand link will generate packets to the destination and will bring up the link.
