Well. Bit 53 seems to start the V7 definitions. You might have looked at something pre-V7
then?
That sounds right; I'm going to guess it's V6.

Clearly a bunch more defined than you have. However, I would not dare explain what they
all mean. Some I might be able to figure out, but some I suspect I might not understand at
all.
Interesting. The list I have in PyDECnet stops at bit 52, I'm not sure
why. Perhaps that's the highest I saw in the VMS microfiche.
