You might want to see the data sheet on the KS0070B driver chip at
http://www.asamicros.com/pub/project_source/ks0070b.pdf
The commands for programming start at page 12 of the pdf file. Its a matter of sending the correct sequence of binary 1's (+5v) to the controller.
As an example 00000001 will clear the display
and 00000010 will return the cursor to the home position.
Any help ?, yes no let me know.
Regards

1. It could be your program. Are you sending the characters over & over. You only need send them the once and they should get stored in the LCD RAM.
2. It could be a faulty LCD module. Have you tried any others.
