Although i remember that someone from NL > at least read the specs ;-) Well, that was the V.120 spec (even though I have read the V.110 spec as well, and it is equally unenlightening). My observation is that the ITU V.120 spec of 09/96 does not match what I see when I trace a V.120 connection. This means I don't understand the spec, probably; the alternate hypothesis being that noone bothers to implement the spec. So, I'm not even going to touch this code unless someone with access to a good protocol analyzer can give me a detailed protocol trace of a V.120 connection between, say, a PC running the Teles software and a Compuserve POP (and even *then* I'm not promising a thing). V.110 should be similar to V.120, but then again, one would expect V.120 implementations to be similar to the spec as well :-) Cheers, -- Bert -- Bert Driehuis, MIS -- bert_driehuis@nl.compuware.com -- +31-20-3116119 The grand leap of the whale up the Fall of Niagara is esteemed, by all who have seen it, as one of the finest spectacles in nature. -- Benjamin Franklin.
