Ih Phase IV, mostly they are listed in the Session Control layer spec, since this is
considered part of that layer -- with the exception of the ones that have special meaning
in NSP.
The Phase II NSP document also lists them, and has one more (24, flow control violation).
I don't recognize 10, 11, 21, 22, and 32 from anywhere; those may be imaginary or they
may be OS specific codes that some OS added. Does DECnet/20 generate those?

Where are all of these spelled out? I had looked in the Phase IV NSP functional
specification (NSP401.TXT) for them, but only a few seem to be there.
The background is that I have further enhanced Kermit-20 to use direct monitor
connections when doing remote terminals and also to print the text of a disconnect. I
duly copied over the list in MONSYM, Etc., Etc., Etc. Earlier this week, I put some more
contingency code into FAL to handle server crashes. Basically, the controller would sit
in a loop forever restarting crashed server (DAP) forks. Now it waits a while and stops
completely after a certain number of restarts.
While I was at it, I checked its list and found that it was missing text for disconnect
codes 10, 11, 21, 22 and 23. Well, I put it in but got to wondering what others there
might be. Right now Tops-20 Kermit and DAP know about the following:
Code
Reason Text
0
Reject or disconnect by object
1
Resource allocation failure
2
Destination node does not exist
3
Remote node shutting down
4
Destination process does not exist
5
Invalid process name field
6
Object is busy
7
Unspecified error
8
Third party abort)
9
User abort (asynchronous disconnect)
10
Invalid node name
11
Local node shut down
21
Connect Initiate with illegal destination address
22
Connect confirm with illegal destination address
23
Connect initiate or confirm with zero source address
24
Flow control violation
32
Too many connections to node
33
Too many connections to destination process
34
Access not permitted
35
Logical link services mismatch
36
Invalid account
37
Segment size too small
38
No response from destination process
39
No path to destination node
40
Link aborted due to data loss
41
Destination process does not exist
42
Confirmation of Disconnect Initiate
43
Image data field too long
