Subject: jnos40 and Brkints on data engine
To: tcp-group@ucsd.edu
I have been attempting to run jnos40 in my data engine. I use a 1200
baud modem in one side of the data engine and a 9600 baud modem
in the other side.
I seem to consistently get quite a few Brkints (break or abort
interupts) in the 9600 Baud port. "Quite a few" is about 100
per second. My impression is that the data engine is servicing
so many interupts, that it has no time to do much else. It is
related to the 9600 baud modem, cause if I take it out, I can
do not see this problem. My 9600 baud modem jumpers are set up
as default from Kantronics.
Questions
1) What actually causes the Brkint to happen.
2) Any ideas as to what I could try to fix this.
Thanks

To: tcp-group@ucsd.edu
If anyone has the code that Brian Kantor wrote (Brian doesn't have
it anymore) for Phil's base code that redirects connects to other
protocols, could you please let me know and also upload it to UCSD.EDU ?
Also some folks in Minnesota I believe wrote some code like this
for an older version of JNOS. Could I get a name, callsign, and email
address of someone with it and if possible get a copy of the source?

Subject: WNOS, NOS & NNTP
To: tcp-group@ucsd.edu
I am using WNOS4A8 as an NNTP server. When running on a 486 under a DOS
window I did not experience a memory leak. Then I moved it to a 286 machine
and slowly ran out of memory. But I modified the AUTOEXEC.NOS file and
set the IBUF SIZE to 512, DOMAIN CACHE SIZE to 6 and started WNOS4A8 with
only 6 sockets in the hopes of having more free memory. Using these
setting I apparently am not experiencing the memory leak. Of course there
is very little you can do with these setting.
However I do have a question on how different versions of NOS handle NNTP.
>From what I have determined some forms of KA9Q (like WNOS) issue NNTP commands
that request news articles from another NNTP server and it is up to the
other NNTP server to keep track what has been sent and what still needs
to be sent. Whereas other forms of KA9Q keep track of what has been
received and issue requests to the NNTP server asking for specific
articles.
Can someone expand on this or point me to documents describing what is
happening?
Thanks,
-Stan Kasper
