Steven, No. Yes. I think the strict definition of "connection oriented" relates to layer 3 or above protocols (such as TCP). Of course, PPP does negotiate a logical connection between two end points. But it does so at layer 2. And you are absolutely correct that PPP does NOT ack data packets with control characters in the way I described earlier. I was merely refering to the "ACK" that you will see ONLY during the PPP negotiation phase (and only if you are using a sniffer or debugging ppp negotiation). Bisynch protocols use a similar mechanism throughout data transmission that PPP only does during negotiation. Sorry for adding to the confusion. The terminology is bad enough without my help.
