Data Format
This image file can be sent as 8-bit data or 7-bit ASCII Hex. The 7-bit version
sends the same data as the 8-bit version, but each byte is sent as two ASCII Hex
characters.
Example:
A 50-pixel by 50-pixel box located 10 pixels down and 10 pixels to the right of
the origin. Note that the X-Cursor is set to pixel 8, and the data starts with the
first two bits equal to zero so the box starts at column 10.
As 8-bit data:
Command Description
0x58 0x08 0x00 X-Cursor at pixel 8
0x59 0x0A 0x00 Y-Cursor at pixel
