(3) Setting the video display size and position
Setting commands 6Fh 73h 69h 7Ah 65h 20h 31h 20h [H.size] 20h [V.size] 20h [H.pos] 20h [V.pos] 0Dh
H.size, V.size, H.pos and V.pos are expressed with ASCII codes.
Example: When the display size is 320x240 and the display start position is (0,0),
H.size = 33h, 32h, 30h (=320)
V.size = 32h, 34h, 30h (=240)
H.pos = 30h (=0)
V.pos = 30h (=0)
the above are expressed with ASCII codes. The send commands are as follows.
6Fh 73h 69h 7Ah 65h 20h 31h 20h
33h 32h 30h 20h 32h 34h 30h 20h 30h 20h 30h 0Dh
