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,
