Yes, I knew about Zero being legal and I think I had already remarked about that in some previous thread.

Did you ever have one of those days where you just can't seem to find the perfect word?  I didn't mean "interesting" as in 'wrong', but rather interesting as in something that caught my eye.  Why?  Beats me.  I mean, I didn't want to just write "Golly!", so that was as close as I had patience to get.  "Of note" didn't work, either...

I think you're probably correct about the Tops-10 DAP implementation.  It needs further productization and testing.  It is possible with simple commands from the Tops-20 NFT client to so completely hang Tops-10 FAL that the service can't be restarted in any obvious fashion.  You have to reboot.  That's probably not the last word on the thing, but it is about as far as Bob and I got looking at it.  I didn't want to troubleshoot by hanging VENTI::...

On the other hand, Tops-10 FAL is whaaay cool for supporting other transports besides DECnet, the Tops-10 only networking protocol (whose name slips my mind).

I have the sources somewhere on VENTI2:: so I don't need to have VENTI:: up to look at them, but that's a rabbit hole I'm not going anywhere near for the moment.

I don't know what that "DECnet" field is.  As for buffer size of zero, that's legal, the DAP spec says it means "unlimited".

That matches what I see from RSX. Tops-10 looks almost broken, if you as me. I suspect it just wasn't developed and tested much in the latter days, compared to TOPS-20.

I've been testing my changes to Tops-20 NFT and ran into what what I thought were some perhaps interesting results, viz:

   NFT>*i twonky*
   Attempting connection to TWONKY:: [31.37]
   Maximum buffer size: _0!_
   Operating System: Tops-10, File System: Tops-10
   DAP: 7.0, DECnet: _0.0_
   NFT>*i ostara*
   Attempting connection to OSTARA:: [31.15]
   Maximum buffer size: 4096
   Operating System: Ultrix-32, File System: _13 (Unknown)_
   DAP: 7.0, DECnet: 1.0
Note that I am clipping the capability display for these examples. By "interesting", I was surprised to find that Tops-10 is reporting a buffer size of zero, but more by it reporting a DECnet version of 0.0.
