I wouldn't swear to it, but when we were a field test for 6.x, there was some
internal documentation on DECnet over the CI. I think there is still some kind of write
up on it, somewhere.

I'd be interested in DECnet/20 and DECnet/VMS docs about CI use.
Some skimming of the VMS 4.0 microfiche listings says that yes, CI support is in there,
and the CI driver (CNDRIVER.MAR) in the comments refers to Phase III, and speaks of
"tributaries". So it looks like CI was treated like a sort of DMP-11, a
multipoint datalink with explicit connection state to each remote station.
I noticed something else interesting while looking over some NETACP listings: the code
appears to support Phase II, III, and IV all in one system. I had no idea anyone had done
that before I did in PyDECnet. Does anyone here have experience with this? It would be
interesting to see how well it works.
