Did you follow up > Brian's suggestions? What happened? Maybe he's just the bloke who uses SLIP instead of PPP, or the bloke who wants to work on ISDN code for the 4 second reconnect. Or maybe he's like me, and he can't get the thing to idle disconnect because of the !@#$! keep-alives that are near-impossible to turn off if you have a local net as well. There are a lot of general uses, besides PPP, for interface event notification. PPP just uses one of them. In answer to te original question, yes, it's possible, if you are the packet transporter and use the tunnel devices, just like iijppp, to let you sleep waiting for a packet "event". But there is no general event interface, even though it's becoming more and more of a kludge to not have one (e.g.: say I want to register for a directory change event because I'm a file browser, and I want to see files show up immediately, not after 10's of seconds when my poll-the-directory timer fires off).
