Send commands
An area is requested as a picture. The width and height are sent in pixels
first of all, followed by the actual picture data, via RS232.
n1=0..7: load I/O port <n1> (1=H level=5V, 0=L level=0V) n1=8: load all 8
I/O ports I/O0..I/O7 as 8-bit binary value
This command is used to query the display type. 3 bytes are sent back: X
resolution, Yresol., 'H' (e.g. 240, 64 (pixels), horizontal picture)
