Knner du fr att knpa lite med din 337'a under semestern?

Hll tungan rtt i mun bara, det kan vara lite vdligt om du inte vet vad du
pysslar med. Ett tips i all vlmening, prova dig INTE fram till andra kommandon
n de beskrivna, bde flash och e2prom r raderbara i test-mode samt att du kan
rka stlla in din mobiltelefon att stra GSM-systemet.

OBS!  Din 337'a r INTE lngre typgodknd efter denna modifiering!  OBS!

Instructions how to enable the built-in calculator and rbs-info on a Gx337.

Connect RS232 to phone via an TTL to RS232 converter.

NOTE! You can NOT connect the RS232 directly to the phone,
      you MUST use an TTL to RS232 converter!

        Pin 8   DC GND                           ->  ComPort GND
        Pin 11  RXD (TTL serial data TO phone)   ->  ComPort TXD
        Pin 12  TXD (TTL serial data FROM phone) ->  ComPort RXD

Connect external 5 volts to Pin 9 (FLASH 5/12volts input)
(Pin 6 SWDC5 [5 volts out] to pin 9 may also work, but have not tried it)

Pin 1 is leftmost pin (near Mic), when looking at the front/bottom.

Set ComPort to 9600bps, 8 data, 1 stop, no parity.

Power on phone by pressing "NO/ENDpwr".
When performing its powerup sequence the phone will send two ">>"
(ASCII 62 decimal) characters. Within 1 second, reply to it by
sending the 4 character sequence "TP1<CR>".

If everything whent fine you should get the "OK" prompt back.


Test the TEST PROGRAM by sending the commands terminated by a <CR>:

        PROG 0          (Test program product number info)
        PROG 1          (Test program product date info)
        PROG 3          (Main application product number info)
        PROG D          (Main application product date info)

Now, enable the built-in calculator and rbs-info, send the command:

        EEWR 047A 01

Wait for the OK prompt, power off the phone and disconnect it
from the interface cables. Powerup and browse thru the menus, enjoy!

To revert to the default setup, use the command:

        EEWR 047A 00
