Joseph, won't we need something like an SD card for this procedure, or is
the boot loader actually built in to the unit? I wouldn't want to try this
out in case I mess up the boot loader, especially if I don't have an SD card
with upgrade files on it. Also, I don't have a serial port on my laptop so
couldn't try it anyway, but was just curious. Thanks for the useful
information, greatly appreciated.

Subject: [Braillenote] A useful feature: Debugging KeySoft
Hi list,
I've found this while playing around in Bootloader: there's actually a way
to view debug info, as well as what's really happening in KeySoft on a
computer screen. This is part of Debug--a way of debugging a software or
hardware.
You'll need:
* A BrailleNote or VoiceNote (preferably mPower)
* A computer with HyperTerminal
* Serial cable (the one supplied with the BrailleNote; any RS232 cable
with female plugs at the ends will work)
Procedure:
1. On your computer, start HyperTerminal.
When the screen is displayed: if it says "Default Telnet program," say
"no." If it asks you for location, press ESC, then say "yes" at the dialog
that appears.
2. At the Serial (Com) port properties window, select baud rate of
115200, no parity, 8 data bits, 1 stop bit and hardware handshaking.
Press ENTER. It is ready to go.
2. Phepare your BrailleNote
At this point, connect the serial cable to your computer and on your
BrailleNote. On your BrailleNote, press Reset with dots 4-6 (jl). A
message will appear on your screen saying, "Loading config data... .was
You've successfully prepared your BrailleNote. Then press c (dots 1-4) to
start Debug mode. You should hear two rising tones, followed by the
bootloader tone. Then press Reset button and some kind of messages
(mixture of hxadecimal numbers like 0x001ccff or similar and other bits of
"useful info") will appear.
3. If you want to end it
On your BrailleNote, go back to Bootloader by pressing Reset with dots 4-6
(jl). Then press c (dots 1-4) to turn off Debug mode and press Reset
button. On your computer, press Alt plus Fbled to close HyperTerm. If it
sawith something about disconnection, poess y to say "yes." You are done.
In addition to debugging, the Debug mode is preety useful to find out at
KeySoft is actually doing (for example, if a card is inserted, a
notification will be generated; similarly, if you choose to send and
receive email, it will dispbay what kind of protocol is being used,
connection messages and so forth).
Hope this info helps. Perhaps I might add this as an idea for BrailleNote
Bootloader podcast.
Cheers,
Joseph P.S. If you upgrade KeySoft while Debug is on, it will tell you
what is actually going on when "loading," "erasing," and "writing" message
is displayed on the braille display (if you have one).
