If the client needs a reliable, connection oriented service, then Link Up/Down/Reset events should be signalled. If the client just needs a datagram service, then there may not be a need. If you are building a generalized service interface, for multiple possible uses, I'd put in a full suite of control/status interface primitives. >Any references to HDLC docs, especially those available online, would also >be appreciated. Thanks. -LDV I's recommend getting the relevant ISO standards, but they are not going to found online. (sorry I'm at home and don't have the numbers handy) Art
