Finding out when xbee associates

According to the manual I thought you could find out from the coordinator when an Xbee end device powers up and associates; the coordinator is supposed to get a Modem status response. It doesn't happen. I'm using ZNet software. Anybody managed to make this work?

Naw, I think I misread that - nobody tells anybody anything when that happens. However, for those that are interested, now that I mentioned it, what I'm going to do is have the coordinator look at the 16-bit address of anybody talking to it and if the talker is not in the comm map then a new node discovery has to be initiated so we know all about him.
