Please excuse this Newby asking a question all the rest of you know the
answer to. How do you do a brainwipe. I presume it is eliminating
everything from the memory but without recorse to the manual I would
not know how to do it.

Regards,

Michael

and terrible defeat... (was Re: [NTLK] Newton=20=<br>&gt;<br>&gt;GPS prob:
&quot;GPS: 0&quot; -----)&quot;<br>&gt;<br>&gt;<br>&gt;Dear
all,<br>&gt;<br>&gt;<br>&gt;a(nother) lesson in Humility was taught and
learned this morning. After=20=<br>&gt;<br>&gt;trying every possible Init
command combination (\$PRWIINIT and \$PRWILOG,=20=<br>&gt;<br>&gt;or \$PRWIINIT
and \$PRWIILOG?, etc.) and completing this very=20<br>&gt;fascinating
(boring, actually) series of experiments, the only thing
I=20=<br>&gt;<br>&gt;could try on my own was a deep Newton brainwipe and
reinstalling from=20<br>&gt;backups, just as Adriano suggested (remember: HE
had success with the=20<br>&gt;same receiver on a freshly brainwiped Newton
w/o any command strings!).=20=<br>&gt;<br>&gt;Needless to say: As anything
Adriano says, this worked brilliantly.<br>&gt;<br>&gt;<br>&gt;I have done
the following:<br>&gt;<br>&gt;1. Back-up Internal storage to Storage Card
1.<br>&gt;2. Back-up Storage Cards 1 + 2 to desktop.<br>&gt;3. Remove Card
1; erase Card 2, install GPS Map on it. Remove Card 2.<br>&gt;4. Erase
Internal storage.<br>&gt;5. Insert Card 2 (which mounted nicely), start GPS
Map and wait. GPS=20<br>&gt;Map acquires position -- worky.<br>&gt;6.
Restore complete Internal storage from backup on Card 1. Start
GPS=20<br>&gt;Map from Card 2 -- no worky.<br>&gt; Assumption 1: Problem is
on Internal store.<br>&gt;7. Remove cards, brainwipe Newton again.<br>&gt;8.
Insert Cards. Restore all information, but no packages to
Internal.=20=<br>&gt;<br>&gt;Start GPS Map -- worky.<br>&gt; Assumption 2:
The error lies with a package (buggy?
corrupted?=20=<br>&gt;<br>&gt;conflicting with GPS Map?).<br>&gt;9. Install
packages by letters, reboot and try GPS Map (all
&quot;a&quot;=20<br>&gt;packages, reboot, test, then all &quot;b&quot;
packages -- so I can say in which=20=<br>&gt;<br>&gt;batch of installed
packages the cause might lie). -- This should have=20<br>&gt;worked
perfectly, but didn't; very weird, as in: no worky, then I=20<br>&gt;freeze
the packages of the last batch -- still no worky.<br>&gt; Assumption 3:
WTF?!<br>&gt;<br>&gt;10. In the end, I had everything restored to the
Newton, but no worky.=20=<br>&gt;<br>&gt;So I went and froze ALL packages in
Internal storage and rebooted=20<br>&gt;(which I didn't do after freezing in
the last step... shoulda done that=20=<br>&gt;<br>&gt;after each freezing!).
GPS Map check: worky.<br>&gt; Assumption 4: After freezing, something stays
alive in memory =<br>&gt;which=20<br>&gt;reminds Newton that there used to
be this thawed package, and this=20<br>&gt;memory is gone after
reboot.<br>&gt;11. Then I unfroze the packages letter-batch-wise, rebooted,
and=20<br>&gt;checked again. I repeated this, until I found a batch that
broke GPS=20<br>&gt;Map position acquisition again. Then I went through a
cycle of freezing=20=<br>&gt;<br>&gt;one package of this batch, rebooting,
GPS Map checking, then the next=20<br>&gt;-- until GPS Map worked again.
The last package processed was the=20<br>&gt;culprit... (Deleted this for
the time being. Needs
more=20<br>&gt;investigating...)<br>&gt;<br>&gt;<br>&gt;E finalmente, amici
-- SUCSESS AT LONG LAST! HOORAY!<br>&gt;<br>&gt;<br>&gt;Another observation:
I have checked TeleType GPS performance, too. I=20<br>&gt;can now get a nice
reading in Position mode (more precise heigth=20<br>&gt;reading than GPS
Map, plus I just LOVE the flashing satellite dish=20<br>&gt;icon! ;=3D} )
and the Monitor mode doesn't stall anymore. Neat.<br>&gt; Bonus: The Monitor
now only shows GGA, RMC and VTG sentences =<br>&gt;coming
in=20<br>&gt;(unlike last week...) -- just like I wanted it! Yay! Seems the
Init=20<br>&gt;strings I'd used in GPS Map configured the receiver, which
keeps the=20<br>&gt;settings in its RAM as long as its rechargeable battery
lasts (32 days,=20=<br>&gt;<br>&gt;recharges during normal use; after longer
intervalls it will be reset=20<br>&gt;by the Init strings in GPS Map).
Another brilliant triumph for Team=20<br>&gt;Newtonia!<br>&gt;<br>&gt;So, I
was very happy. Well, as things go, my pure and childish joy
very=20=<br>&gt;<br>&gt;soon fizzed away, when I tried to get my original
data restored to Card=20=<br>&gt;<br>&gt;2. The restore went nicely, BUT
THEN...<br>&gt; LIGHTNING STRIKES! Restore went great, the Newton restarted,
and =<br>&gt;when=20<br>&gt;it wanted to activate the packages on Card 2, it
just stalled. I forced=20=<br>&gt;<br>&gt;a reboot (pwr + reset), removed
card, waited until Newton was up and=20<br>&gt;had activated all packages in
Internal and Card 1 stores. Then I=20<br>&gt;reinserted Card 2 -- after a
couple packages, the activation stalled=20<br>&gt;again (not always on the
same package, though...). ARRRGH -- RATS!!!!<br>&gt;<br>&gt;Well, seems like
I have a new Mayday call:<br>&gt;<br>&gt; *** How can I get the
=A7\$%&#!-card to activate its =<br>&gt;=A7\$%&#!-packages?<br>&gt; Or how to
erase the card completely so I can try the restore =<br>&gt;again?
***<br>&gt;<br>&gt;<br>&gt;Oscillating between crystal-clear tears of joy
and gratitude and sheer=20=<br>&gt;<br>&gt;disgust, horror and
contempt,<br>&gt;<br>&gt;yer pal 'Kasko.<br>&gt;<br>&gt;<br>&gt;P.S.: Okay,
and next week I'll get the serial-to-USB cable the=20<br>&gt;manufacturer
offers, so then I can hook the receiver up with my ole=20<br>&gt;PowerBook.
Say, what's a good Navigation + GPS application for OS X=20<br>&gt;(with
European topographical maps in 1:50.000 or even
1:25.000,=20<br>&gt;preferably)?=<br>&gt;<br>&gt;--<br>&gt;This is the
