7.3.3 Upload Font (254 36 [ref] [file size] [file data])
to be used for this font. File size is a 2 byte value that must be calculated by the host before the transfer takes
place.

A font file consists of a header, a character list and character bitmaps.
The header consists of;
• Placeholder for actual EOF (2 bytes, use 0xFF 0xFF - these bytes will be set to their final value by the
• Nominal character width (1 byte)
• Absolute font height (1 byte)
• ASCII value of first character defined in this file (1 byte)
• ASCII value of last character defined in this file (1 byte)
• Offset to character bitmap (2 bytes)
• Actual width of this character (1 byte)
