There are a set of perl scripts that do this (called tpage), and I believe
perl has been ported to MS-DOS.  There's also a mailing list for the IPX
protocol, though I can't remember the address right off hand.

I would suggest archie'ing around.

I've done this with analog circuitry, and what gave me the original idea was
making homebrew headphones.  Using what I had at hand resulted in speakers
with different characteristics, and created spatial displacement - and sure
made the pileups easier to figure out, especially as a novice.

Well, I decided that the engineers at RS couldn't be so dumb as to
design a radio that uses the same battery pack interface as Icom, but
burn something out if you actually tried to use some other brand of
Icom-interface battery besides theirs. So, I slipped on my
Periphex BP-8S (9.6v) battery pack and ........ it works just fine!

Still, I'm not sure if you can use a 12v battery pack though, but I'm
willing to bet you can.

I had that problem myself until I realized I forgot to put my TNC
(PK-232) into KISS mode.  Regardless of your make/model, the book can
tell you how.  If the TNC has battery RAM, you can put it in KISS mode
with any regular packet program and leave it that way.  Then in NOS, it
will be there.

If that still doesn't do it, e-mail me and I'll send you my
AUTOEXEC.NOS.

Thanks for the offer, but I finally figured it out.  The problem was that
autoexec.nos was calling another program, too, called kisson.dia
It was this other program which had a baud rate set to 4800.  Autoexec.nos
was set to 9600, so it was talking to the TNC, but the other program also
needed its baud rate changed.  As soon as I corrected that mistake, the STA
LED finally went back out, and I could connect.

Now, for some success in connecting to other IP stations via the one I
have my IP address from...

73,
Scott

You can use either form of the 'callsign @ BBS' string on most BBS
software that I've used.  The 'standards' say that the '@' should be
surrounded with white space, but that BBS software authors should code to
parse the string without the white space.

I have a Packard-Bell 386 (Axcel 100) located about a foot from the rig, and
it's absolutely quiet.  Unfortunately, the monitor I have is a Compudyne
14/640V, which generates an incredible amount of hash between 10 and 20 meters,
with 15 meters being by far the worst.  I've tried numerous "fixes," but the
only thing that works is turning the monitor off when operating SSB, and then
turning it back on to log the QSO.  Frustrating, but it works!

On CW and the digital modes, the bandwidth is sufficiently narrow that I can
normally get a decent signal-to-noise ratio even with the monitor on, so I
don't have to operate RTTY with the monitor off, which would be a REAL
challenge.

OK...please knock it off.  I 'member the last time this happened from
a fidonet node, and it was lousy then.  Please set up your parameters
so that stuff coming off the net doesn't get echoed back!
