TOPOL?? Hmm...? No, I hadn't heard of that, either.? It sounds almost
familiar, but I don't know why Tops-20 would be asking for it because
it? doesn't appear to be serving it, viz:
This is node VENTI2??? NSP version 4.0.0??? Routing version 2.0.0

The numerics for the objects would be the following (last column with SRV:

So, no TOPOL that I can discern.? See if you can get me a bit of a
packet trace, would you?? I'll have a look around.
If it's in the NICE process (NMLT20), I'll be out of luck because they
never released those sources, but maybe it's in ROUTER.

The 4.x DECnet over DDCMP DUP/KMC for 2020 has reduced "segment size'
from 576 to 390 or something like that due to limited buffer space.
256 actually.
Why, I don't know, but since that is communicated to the other end in the connect
initiate or connect confirm message, it doesn't cause any problems only than some
possible drop in performance.
PyDECnet can talk to those Phase II nodes, at least to some extent; it needs some
cleanup. The intercept support in particular is incomplete.
Speaking of which, I noticed that TOPS-20 upon connecting sends to its neighbor (my
PyDECnet router) a connect request for an object named "TOPOL". That suggests
some sort of topology information service, which makes sense. But I have no idea what
that thing does, what requests it excepts and what its reply should look like.
Very long shot: does anyone have any idea? Any way of getting a network trace, perhaps?
