Mister_e must have interpreted the table; this is what I would like to be able to do too.

So, my question was more precisely to:
a) understand the definition table (in post #19);
b) learn how to use the informations on there.
Look at the datasheet for the LCD controller, specifically Page 26.

"Display On/OFF"

The 8 bits for the register = 00001DCB

D= display 1=on 0=off
C=cursor 1=on 0=off
B=blink cursor 1=on 0=off

so "00001100"

Will give Display On Cursor and Blink off which is $0C

$0C is the command to turn the Cursor OFF but it also turns the dsipay on as well

$0E will turn the display on with a cursor
