& d @ - Disable underline
Once underlining is enabled, any positive horizontal movement
causes an underline to be drawn. Positive horizontal movement
includes the printing of text and positive horizontal cursor motion.
When fixed position underlining is enabled, the underline is drawn
five dots below the baseline and is three dots thick. (The baseline is
the dot row on which all of the characters in a given line appear to
stand, see Chapter 11.) When floating position underline is enabled,
the underline position is determined by the greatest underline
distance below the baseline of all of the fonts printed on the current
line. (The underline distance for a font is defined in the font header,
see Chapter 11.)
Note The underline and the underscore character may not necessarily be
aligned or be the same thickness.
