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.

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.

I don’t remember what we used for DECnet-SCO but that was another official implementation.

It doesn't do network terminals in part 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.

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.

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:

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.
