I have done this just now:
1. in Unfiled/Prefs/Recording, switch to Line-in (there's also
somewhere a nice hack to to this from Button-bar, I think).
2. in Notes, open new Recording, start audio recording, pause recording
(else you'll create a huge recording of nothing, until all free storage
is used up and the Newton gets a hiccup from that). GPS: LED lights up,
acquires fix (LED starts flashing).
3. Start GPS Map:
3.1 "Waiting for GPS Data!"
3.2 "GPS: n/a" (LED still flashing...)
-- aborted test after a few minutes w/o any change (besides message
that the recording had filled up the storage on my Newt). Brilliant
idea, well worth the attempt, thanks for thinking about my prob, but no
success.
Observation: I got "GPS: n/a", which means the app didn't get to see
the GPS receiver at all. When I'd sent the Newton to sleep and woke it
up again, I got a popup telling me "Device in use by another
application".
Interpretation: The recording apparently "grabs" the serial input, and
GPS Map doesn't get to read it. Or what do you make of it?
The current problem just has to be the too-many-sentences,
too-short-intervall prob, check the GPS Map-FAQ
http://tools.unna.org/wikiwikinewt/index.php/GPSMap which I've started
yesterday. But what really frustrates me is that Adriano didn't use ANY
Init string, and got it working two weeks ago -- the very same
receiver, just on his own Newton! With exactly the same settings!
Arrrgh! Rats! ;=}

And that was with the very same AQ-300 I have right now in front of me!
And the same settings! Rats!

How can I found out which soup or pref is corrupted? Or if I want to
delete all related packages and reinstall -- how can I find all soups
and stuff so I can eliminate them?

I had some strange observations before, e.g. my Newton is the only one
in the whole multiverse where Eckhart's SmallExtras doesn't work.
TeleType GPS didn't totally crash, though. Just the Monitor crashed,
reporting the error I'd mentioned last week. Then I could still switch
to other screens in the application and even close the application
nicely. I think the Monitor just stalls, because it has a case of GPS
overload... Less sentences, more seldom, that should fic that, too (but
at least TeleType GPS DOES get a position fix!).

Haven't matched this to some funny behaviour before... And in our case
here, it concers two applications who are not so happy. So I think as
they don't share any soups and prefs (I guess), that's not very likely
to be the cause, no? But then, the receiver worked for Adriano...
Arrrrrgh! Rats!
Is there a way to log on to such a device on Newton's serial via
terminal and configure it? Like, dunno, telnet to it or something?
Maybe the GPS can be configured this way...? What could I try?
