Hey. Thanks for those additions. Any machines on HECnet I can check against?
Not that I know of at the moment. I?m just in the process of downsizing and moving. Once
that?s done I?ll be looking for access to HECnet.
John.
NFT under RSX have this wonderful functionality that
seems to be missing in all other implementations:
.nft venti2::/id
NFT -- Version V9.0
Local NFARs V8 DAP V7.1 Buffer size= 2064. OS=RSX-11M+ FS=FCS-11 DC=Yes
Remote FAL V2 DAP V5.6 Buffer size= 4096. OS=TOPS-20 FS=TOPS-20 DC=Yes

Thomas, I'm not sure where you got that list from.
It seems slightly mismatching what I can find. Looking at the NRT code in RSX (which uses
object 23, and is shared by code in RSX for connecting to both RSTS/E, VMS and Tops-20), I
find this:
1 RT-11
2 RSTS/E
3 RSX-11S
4 RSX-11M
5 RSX-11D
6 IAS
7 VMS
Those are the documented values for the configuration message that I can find.
However, extrapolating from this, in NFT/FAL, there is a much more extensive list, which
seems to align with this list, which contains:
8 TOPS-20
9 Tops-10
10 RTS-8
11 OS/8
12 RSX-11M-PLUS
13 COPOS/11 (TOPS-20 frontend)
14 P/OS
15 VAXELN
16 CP/M
17 MS-DOS
18 Ultrix-32
19 Ultrix-11
20 DTF/MVS
25 Windows NT
26 Linux
Now, Linux is a value I believe I added just based on observation, so it's much less
official. But I think all the other ones are ones DEC did assign. Unfortunately, I think
Windows NT was also added by me, based on observation of Pathworks. So I do not know what
the values between 20 and 25 could/should be.
The current version of DECnet for Linux I maintain on github uses 192 for Linux
which comes from the user-defined space so I could completely avoid any conflicts with
standard implementations. 22 was for MacOS (the original O/S for the 68K and PowerPC)
where DEC resold a third party implementation (Thursby I think). I don?t remember what we
used for DECnet-SCO but that was another official implementation.

because it has no code to handle the out-of-band or meta-data that one finds on TVT's
(like IAC's) or CTERM's.

Tops-10 and Tops-20. Once you've read the initial configuration message and decided
what to do, you basically never have to bother with meta-data. Because I'm trying to
look at an NFT issue between Tops-10 and Tops-20, I needed another transport mechanism and
modifying Kermit-20 to do DECnet 36 NRT's seemed like an easy hack. Since Tops-10
Kermit isn't making an outgoing connection, it is none the wiser.

the few cases where certain operations don't make sense or otherwise wouldn't work
(like setting the terminal speed). Another thing I'd like to prevent is Kermit-20
bothering non-36 bit systems. This is easily enough done by checking some 'magic'
bits in the initial configuration message and restricting by OS type. This raises two
questions:

if it's documented, period. All I have is are some notes that Johnny wrote up in the
process of reverse-engineering it and very kindly gave me. They are certainly fine for
this particular implementation, but I was just wondering what else there might be. Plenty
for LAT and CTERM, but I don't think I've stumbled over NRT.
