DECnet-Plus isn't
able to connect, or at least reliably connect to all OS's that can
potentially be on HECnet. I forget what all OS's I was having issues
with, I know one was RSTS/E v10.1, but I want to say it also included
VAX/VMS. Once I *upgraded* my Alpha running OpenVMS to DECnet Phase IV,
all these issues went away. These were things as simple as SET HOST.
It's probably that DECnet-Plus (Phase V) cannot speak with DECnet Phase III (such as
on RSTS/E and TOPS-10/20). That's my guess anyway.
Phase V should be able to communicate with VAX/VMS since that's Phase IV, which is the
gold standard of DECnet, IMHO.
