Okay, I give up. Is there an IBM publication, formal or otherwise,
that actually defines the PU2.1 <- (NOT PU2.0!!!) local channel
protocol, including ___XID___ negotiation?

I have enough references, mostly contradictory, that such a protocol
exists and that it is different from the PU2.0 (AKA 3274-1a) protocol.

Please mail me a clue.


And while we are on the subject. The IBM publication "Type 2.1 Node
Reference" rather clearly states that all 2.1 nodes support XID
format three (3) while the IBM publication "Network Product Formats"
rather clearly states that a channel 2.1 link uses XID format two (2).
(But then again consistency is the hallmark of little minds.)
