how can i use the display mode d3 and db for afx 2.0 plus?
the moment i do something like outportb(2,0xd3) or outportb(2,0xdb) or

mov al, 0xd3
   out 2, al

,
the calculator screen will display a lot random dots that change positions with every press of any buttons, and i'm forced to off the calculator. how should i go about changing display mode?

the problem is, that this mode represents the display in an other
way than the CASIO software expects it. The changing dots come from the casio programs that access the Video memory as if it was the same but you changed it.

You really need to change it back before exiting your own program.

Btw. don't mess with these things if you don't know what you're doing. Its not like a resolution but only helpfull if you want to
code a program using this modes (Grayscale, Line Mode ...)
yourself. It is like setting the video card in the BIOS of your PC. YOu won't set it to PCI if your driver can only access the card on AGP will you?
