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

8
Third party abort)
9

/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

32

33
Too many connections to destination process
34
