I disagree, Erich. I think it's as much a part of radio as contesting,
dxing, experimenting - all those different modes. Frankly, it seems to me
that traffic handling and bbs's are the thing for which packet is most
suited. Voice communications seem to me to be far more efficient for real
time. This based on holding a ticket for 40 years now and getting into just
about everything I could. :)

I was recently surprised to see references to ka9q code in a package
of Ftp Software's PC/TCP for dos. This package comes with some
winsock stuff (I think...), and although the source isn't available, one
might coax an ax25 packet driver into working with it. I suspect that
this is typical of many dos networking packages.
As far as other computing environments, work done for Sunos, and recently
Linux, points in this direction-- these provide kernel-layer interfaces
to the ax.25 world. The chalenge now exists to write software to
bridge between where packet users are today (mostly store/forward bbs
style systems) to something a bit more transparent.

I agree with Larry, realtime "chat" mode is about the worst use for
packet. We have other modes that are much better suited to this type
of use. Packet is useful for the things it can do better than other
modes, and store and forward is a primary example of where packet
is superior to other modes. Packet does that well, but it isn't a
substitute for a microphone when the need is for realtime person to
person communications. Hopefully, as the network speed increases,
realtime machine to machine communications will become an important
application facilitator, but right now non-realtime store and forward
is the niche best served by packet.

Maybe from the standpoint of the user but not from the standpoint of channel
usage. There's a reason the phone companies have gone digital /:) What we
ought to have is packet voice!

Hi Hugh, last time I checked, the initial deployment of IS-54 (digital)
was no more bandwidth efficient than NAMPS (analog). And GSM (digital)
is worse than NAMPS.

Not a bad idea. In the System V world, an AX.25 Streams module would be
cool, though a really good one would allow both AX.25 sessions and
other networking sessions, and would be a multiplexor module, not as
easy as a straight AX.25/IP module. NDIS should be pretty straightforward,
though I have to write an NDIS driver.

No. Well, on second thought, I can. It would suck. Here's a :-) for those

Subject: Packet Ideas Sought...
To: ham-digital@ucsd.edu
I'm thinking this summer about what I might want to do for a
senior thesis in computer science next year, and I've decided that if
it is possible, I would like to do something involving packet radio.
Im still trying to think of something to do, however. I have a few
thoughts:
The focus of whatever I do is probably going to revolve around the
nature of the amateur network as a fairly slow one (1200-9600 baud with
rare exception.) It is also currently almost entirely accessed through
text based terminal programs. There are a few specialty products on
the market, but these are all most entirely specialty terminal
programs. So, I could possibly explore something about the nature of
the interface used to access the services in the network. I could
possibly explore the use of something like an X Window system or
similar open protocol for graphically-oriented distributed,
client-server programs.
Or I could possibly explore the netwrk for another angle, and ask
the question "what services should be provided and how can they be best
provided?" "What sort of changes/enhancements in the network will be
the most beneficial to the user community?" Is there something like
hypertext that will greatly improve the nature of the network?
If you have any thoughts on this, I would appreciate it if you
would drop me a line, or start up a general discussion of it here. I'm
just sort of collecting thoughts at this stage, so anything might help.
Also, if anyone knows of a good source for technical documentation
on AX.25 or TCP/IP or the packet network in general, I would appreciate
the pointers.
Thanks and 73's...

Wow! I'd love to be able to set my TXDelay at 18 (180ms). I currently have to
set it to 40 with my GE Custom MVP. Anyone got any ideas how I can speed my
MVP up? How about mods for 9600 buad?

I thought that most 9600 baud folks were trying to run with a TX delay of 7 to

How about it... What is common for 9600 baud?

Kantronics has just announced a new box that handles one port for 9600 packet
and another for 1200 packet. The HDLC framing is in software. Keep in mind that
there is absolutely nothing wrong with using a software solution. It allows
a MUCH simpler method for providing fixes should a problem be found. Suppose
you find a bug in an HDLC-capable SCC chip? The usual answer to that is to
live with it...
I'm looking forward to trying one of the new Kantronics 9600 boxes...

Hmm. Good point Glenn. I used real TNC2 type TNCs when I was using
TNCs. I had forgotten that the Kantronics boxes are gutless wonders.
Still, I do know that the Kantronics 9600 baud modem that fits the
Data Engine (and the Gracillis PacketTwin) is a G3RUH clone, and will
work with MFJ and PacComm TNCs, though it's physically the wrong shape
to fit in the cases.
