I am not aware of any significant penetration into the asynchronous RS-232 realm by HDLC, mostly due to cost and complexity factors. My design efforts have not been at all targeted at the areas where HDLC use is significant (although it doesn't follow that some of the ideas might not be fruitfully applied there). But I don't want to duck the real question about the practical significance of the theoretical result. By itself, it's not all that significant now, really. But, if it isn't forgotten, it may help make future protocols better. And remember, while I have designed a protocol which incorporates the insight, it does not follow that that is the only thing my protocol has going for it. If you want to consider the significance of the whole, you should probably send for the specs. -Dave Hamaker ...!ucbvax!ucsfcgl!hoptoad!cfcl!dwh
