Solution
¶
Check if the serial port setup is properly made.

Check if the test jig is connected correctly. The
connection is made, by '1:1 PIN TO PIN' method (not
NULL modem method). Only RX, TX signal grounds
are connected.

If you use DOS shell in Windows and COM1 is used
by another DOS shell, exit the program.

No way ! The test jig clears the information after
writing is done. If you force to copy it into several
units, the phone might not work properly.

is completed successfully. Error message appears on
the screen.
¶
If the program halters or is interrupted for some
reasons, and you restart the program, 'WRITING IS
BEING CARRIED OUT BY USING DATA NOT
FINISHED' message appears on the screen. It means
that the data you have read and not wrutten is
restored and ready to write. If you have finished the
program by pressing ALT key and X without writing
after reading, the message 'WRITING IS NOT
ACHIEVED, WILL CARRY OUT WRUTING FOR
NEXT TIME' appears on the screen.

You can clear the error message by pressing any key.
