Subject: RE: [aprssig] APRS messaging break out
Curt,
What would help me is if the messages got into a tcpip stream somewhere.
Do APRS messages on the TNC side "leak" into the APRS stream ?
I am having problems coding perl to "tail" a file.
I can handle tcpip streams no probs
I should get into C coding one day !

The D700 is a great tool for exposing people to APRS, but it is limited.
Two of the issues I've run up against are:
1. The D700 knows nothing of Smart Beaconing. It just keeps beaconing at a
fixed rate no matter what's happening to the location, speed, or course of
the GPS data being fed to it.
2. To the best of my knowledge, the APRS software that works with the D700
requires that you put the radio/TNC into "packet" mode. This takes the unit
out of "APRS" mode and disables the built-in APRS functions of the
radio/TNC. That puts the APRS load on the software running on your
computer. No problem unless you plan to switch back and forth. In my
application, I want the tracker running all of the time when the vehicle is
running, but only occasionally will I have a PC hooked up. Sure, I can make
the switch at the radio/TNC, but I'd prefer something more seamless.
It'd be great if there was a way to let the D700 continue to run in APRS
mode and then have a mapping program that pulls the positions from the
D700. I haven't seen anything like that out there.

OK, there's one advantage.

What is Tracker2?
I don't have a "mapping GPS unit". The mapping feature of my Garmin GPS II+
is primitive. And I don't want to spend several hundred dollars for a
mapping GPS with limited map memory to duplicate what I already have in a
PC running a mapping program. The AvMap mapping GPS accessory that Kenwood
is pushing for the D700 looks great, but it ain't cheap.

Yikes. I don't think I need to plot APRS positions on Topo USA. But I would
like to share GPS position data between the APRS solution and Topo USA.

Yep, that's what it may come to.
Thanks for your input!

Please explain.

Are you talking about just splitting the RS-232 signals from the GPS
between the PC and HamHUD. Please explain.

The ease of using Digi_ned for "messaging" is why I've used it for findu
scraping, qrz lookups, zipcode lookups, WWV, time - local and zulu and
even an Eliza client.
As fun as that is -- I'm on to something even better... I hope.

I use Javaprssrvr running on a Linux box with AX.25 compiled onto it. There
are several ways to run Javaprssrvr on a Linux box without having to
compiled AX.25 on it but with AX.25 compiled you can run multiple
connections to a KISS TNC. Linux just starts treating it like another
interface. (I guess it should work with out Linux programs as well such as
Xastir.) It shows up when you do an "ifconfig". Of course if you find a
Distro with AX.25 already compiled on it your a head of the game. I never
found one so I had to compile my own. As part of the compiling process you
usually have to download the AX.25 Tools Library and it contains a program
call "listen". I use "listen" to write an output to a text file that
contains all packets going in and out of my station every day.
$listen >> name_of_output_file.txt
There are lots of good switches in the man for "listen".
I'm guessing you could then write a Perl script (or maybe just grepping it)
you should be able to pull messages out of it. That is if I'm understanding
what it is you want to do correctly.

Go to the below link then click on "APRS Client Capabilities Chart" on the
left. My feeble attempt at keeping track of features for the various APRS
clients. Anyone with changes/additions for the chart please e-mail me
direct with them. Thanks!

with "other" Linux programs as well such as Xastir: Yes. Xastir (perhaps
multiple copies) plus many other programs can share a TNC or multiple TNC's
this way.

There are distributions that contain working AX.25. SuSE (certain
versions) does. I believe Debian does as well.

Yes. You could either attach it to a local aprsd port or to a local Xastir
server port. I've done so, but not for messaging. I either inject packets
into the APRS-IS (or Firenet) or scan the APRS-IS looking for certain types
of packets, using Perl. Works great.
