Important: The line and column information is independent of the font size!
The area numbers are from 31H (area 1) to 51H (area 32).
If an undefined area is addressed, then the error byte is set to 33H.
The error byte can be polled using the status poll and is reset after the poll to 31H
(section 9.1).
Warning:
When a defined area is opened, there must not be any intersection between the area
boundaries and the boundaries of character in large font. If this is the case, the command
is not executed and the error byte is set to 36H. The error byte can be polled using the
status poll and is reset after the poll to 31H.
