One thing which complicates things is that we have
(roughly) layered protocols in place between the 3174 and the host.
So at the physical level we have channel attached, SDLC, Token Ring and bi-sync.
Above that we have the channel protocols, HDLC/SDLC and bi-sync polling.
Then we may have SNA (which encompasses many options) to transport the data through the
network.
At the top the protocols and frame formats in the Data Streams manual which are broadly
the same but with tweaks for SNA, Local and Bi-Sync.
You can say that again. We never could get HASP running on out 11-750
on BSD. This was about 1984. The Berkeley Systems Group even tried
and no soap. This was a leased line setup with Bell 209 modems.
