Hey Johnny,
OK, so piling in the additional definitions did the trick, viz:
NFT>*i ostara*
Attempting connection to OSTARA:: [31.15]
Maximum buffer size: 4096
Operating System: Ultrix-32, File System: Ultrix-32
DAP: 7.0, DECnet: 1.0
Making progress. :-)
I noticed from some subtle behavior that my code
wasn't accounting for
holes in the tables, which hadn't existed previously. The 'subtle'
behavior in question was that NFT completely wedged. Sigh... Oh well,
alpha test. So I fixed that. I would imagine that OS/2 would fit in
the table someplace as well as pre-OSX Mac OS.
There are definitely holes in the list. I think there were even before
the ones I added. But as I only added ones I have observed, the holes
might very well be for values that have been defined, but that I just
don't know about.
By the way, now that I'm up to date in that
regard, have you got any
capability goodies? The latest I have are:
SY$WLD==1B33 ;Supports Wildcard operations
SY$GO==1B32 ;Supports the Go/No-go option
SY$NAM==1B31 ;Supports the Name message
I'll worry about twisting PDP-11 capability bits into PDP-10.

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.
And assuming that the PDP-10 numbers bits from 0 to 35, with 35 being
LSB, it looks like the bits match what you have in your file (I'm
guessing 1B32 means bit 32 being set). But why the RSX code is only
using 7 bits in each byte/group I don't know. I guess it might be in the
spec, which I haven't checked. And I might also have failed in my
aligning this with your PDP-10 definitions. Anyway, hope this helps.
