On page 74 of the "Inter*Poll Network Administrator's Guide", there is a screen
shot of the "Setting" dialog. The "Lookup Interval" describes, in seconds, how
often NBP Lookup packets are sent to the AppleTalk network.
The "Asynchronous Interval" and "Asynchronous Count" come into play when the
lookup packet or packets do not generate a response. The "Asynchronous Count"
field describes how many times a resend occurs, and the "Asynchronous Interval"
field describes how long (in 8-tick increments) the system waits between
resends.
