Also at ftp.ece.orst.edu in the JNOS40 subdirectory (I forget the path) is
the file set for JNOS40 v0.99 which includes a combined and somewhate
complete Commands Manual for JNOS and JNOS40.  The document files will be
put up separately on the next release.  They are in ascii text and Microsoft
Word (with stylesheet) formats.

If you want, the files are also on CyberGate BBS (316) 688-0915

Subject: NNTP
To: tcp-group@ucsd.edu

Hello:
 
I am looking to get in contact with anyone successfully implementing
NNTP using MFNOS.  Another station and myself are running with one
station configured as the server and the other as the client.  At the
kick of the server, contact is made. A line passes with the word
NEWSGROUPS and the names of the groups with the date and time codes,
and then the response is four periods and a QUIT without any exchange
of postings.  We have the 'nntp ihave' set to 2, but we think that we
may have missed a parameter somewhere, or don't have a directory set up
properly causing the server not to send the message list.  Any help
in the way of a list of properly set parameters and a directory tree 
would be appreciated. 
 
73 de Steve, N2MDQ.

I got nos1itl from another ham who downloaded it from a land line bbs (he 
can't remember where). Maybe someone on the list will know where it is on 
the internet. It has three windows. The top window is the trace window 
(whenever trace is active). The middle window is the receive or command 
responce window. The bottom window is the command window. Commands are 
available to set the sizes of the windows.
One of the hams here who is using net1itl found a doc file for it that 
is REAL CLOSE, so I will start with it.
We have played around with the timing and packet size parms and are 
getting better throughput at 9600 baud, but it still goes to sleep 
sometimes when FTPing.

Yes Virginia, there is an Ottawa PI2 card.  I don't want to be accused of
"advertising" on the net (even though our group is non-commercial), so I
won't give any details here, but I don't think it's out of line to give a
pointer for more info.  Send email (subject and text don't matter) to:

pi-info@hydra.carleton.ca

for details on the new rev of the Ottawa PI high-speed synchronous I/O card.
If you have a problem getting the info, or have further questions, try:

bm@hydra.carleton.ca

Happy Networking in '94 from the Ottawa gang...

In our 56kb repeater, the switch controls what goes on the output.  The data
streams from the repeater demod and from the switch go to a data selector,
and the rts line from the switch controls which input is selected.  The
repeater output is keyed by the or'ed combination of the dcd from the repeater
demod and the switch rts line.  Contention is managed by the switch sensing
the dcd.  The switch has a smaller collision window than the other nodes on
the 56kb lan, so it is less likely to cause collisions.  This arrangement has
worked extremely well for us.

I implemented the same strategy in a 1200bps repeater which uses the modem
in a TNC-2 for bit regeneration.  The arrangement is similar to the one
described by NJ7P and N7OO in the 9th ARRL CNC (1990), but they allow the
dcd to control the data selector, which I think is a mistake... then any
dcd hits (falsing from noise or interference, transmissions from stations
that don't copy the repeater well, etc) while the switch is transmitting
will destroy the packet being transmitted.

Sorry to have to use these other groups like this, but this is the only
avenue I can think of.....

The following two stations need to send me a personal message, so I can
determine a MX record from their routing:

     ron@chaos.eng.wayne.edu
     mwestfal@csci.csusb.edu

Also, for everyone's info.....
If you subscribe to the group and do NOT get back a response in a while,
don't send a second request.... Send me a personal message. Most probably
the request got here, and my routing wasn't complete enough (yet) to
get it back to you. The personal message will give me more info for that.

Once again, sorry to send through the group!
