This should give you what you want and more. Let me know what you think.

X-APRS is the same code as MacAPRS and WinAPRS with all of the same
features. The APRS part of the program has been around for a long time and
is very feature rich.
I have not yet decided about pricing for X-APRS.

the maps won't display on my Motorola Startac. I get a message saying there
is a map image. But it doesn't display the graphic. Are the startac
displays not able to do graphics?

Ok, this is going to be a quick one, since they're actually making me do
real work this week. It's a bit off-topic, but a while back we were
discussing features of a next-generation TNC. I think the consensus was
that for anything but very low power installations you're best off using a
standard PC and linux/bsd/qnx/whatever. With that in mind, would it be
feasible to develop a PCI DSP card (or maybe USB-attached module) to handle
the equivalent of maybe 4 sound card modems? It'd have a standardized
physical and electrical interface (say, 6-pin mini-din connectors) with
integrated PTT. It might have enough processing power to help offload work
from the main CPU.
In the most basic form, it'd be just a 4-port A/D and D/A with appropriate
interfacing/buffering circuitry. A more flexible implementation would be a
decent DSP chip with a good chunk of RAM so you could upload programs to it.
NICs are cheap. If I want to build a linux-based router, I can do it with a
few $12 cards from xxxxxxxx. I'd like to be able to do the same with
packet. If there was a $150 4-port card out there with good software
support, I'd buy one today. Maybe two.
Thoughts, anyone?
Scott, N1VG

I can't speak for all Startac versions, but my old ST7868W was text-only.
Even my new T720 seems to have a text-only browser. And unfortunately I've
got Verizon as my provider, so I can only get BREW-based software. AT&T
allows J2ME downloads, so you can download stuff for free or write your own
programs without spending thousands of dollars.

Subject: OziAPRS - APRS for OziExplorer

People
I have updated my APRS for OziExplorer software (AKA OziAPRS) and
updated the web site
http://www.radio-active.net.au/web/gpsaprs/oziaprs.html. For those that
have not used OziExplorer, it has some of the most extensive mapping
tools of any of the consumer level tools on the market.
The OziAPRS software allows OziExplorer to be used with APRS. It also
allows you to import positions of stations through automated GPS
tracking devices, such as those using radio or GPRS trackers. Since I
emailed last about it I have implemented a few more features, such as
adding more information to the descriptions of waypoints, adding weather
information to waypoints when available, implementing detail windows for
waypoints, having different colours for different waypoint types (Moving
waypoints, static waypoints, weather stations) and having decaying
colours for waypoints allowing the newest icons to be most easally
identified.

I ckd my model # and I have the ST7868W. I guess I'll have to upgrade my
toys again.

Any particular reason you wouldn't just plug another sound card in? 2 sound
cards would give you 4 modems.

Well, come to think of it, there was a VERY limited ability to get graphics.
Generally limited to tiny website logos and such. I remember getting one to
work on a page I developed, but it's one bit per pixel (no shades of gray)
and very low resolution. Not useful for any kind of mapping application.
And it's got to be specially formatted.

Mostly for integrated PTT and the ability to offload some processing from
the host. Maybe it's not such a big deal in Linux, but in Windows anyway
the sound card drivers seem to be kind of restrictive on access to the
hardware. Still, it's hard to compete with $10 sound cards.
Someone here mentioned a 6-pin minidin aux jack on some radios... is that a
standard now? IS there any standard? It'd be cool to be able to just hook
up an S-video type cable straight from a multiport board to the radio.
