69030 Databook
0: Every 9th pixel of a horizontal line (i.e., the last pixel of each horizontal line of each 9-
pixel wide character box) is assigned the same attributes as the background of the
character of which the given pixel is a part.
1: Every 9th pixel of a horizontal line (i.e., the last pixel of each horizontal line of each 9-
pixel wide character box) is assigned the same attributes as the 8th pixel if the character of
which the given pixel is a part. This setting is intended to accommodate the line-drawing
characters of the PC’s extended ASCII character set -- characters with an extended ASCII
code in the range of B0h to DFh.
Note: In IBM literature describing the VGA standard, the range of extended ASCII codes
that are said to include the line-drawing characters is mistakenly specified as C0h to DFh,
rather than the correct range of B0h to DFh.
