Works to me, i can draw using A,W,D,S.
Don't forget to return back to text mode.

Code:
exit:   
  mov ax, 0x3     ; back to text mode
 int 0x10

        int 0x20

Does it work for you? wtf

I've tried windows prompt-DOS and DOSbox but it does not work. All it does is to plot a single pixel and nothing more...

Are you using some Virtual Machine? thanks for answer.
