23.5.7
CC: This attribute is valid from the time set until the end of
a row of a display window, or otherwise modified if set with
Serial Mode 0. If set with Serial Mode 1, then the colour is
set from the next character onwards.
The background colour can be chosen from all 16 CLUT
entries.
TXT: The control character ‘New background’ (1DH) is
used to change the background colour to the current
foreground colour. The selection is immediate (set at) and
remains valid until the end of a row of a display window, or
until otherwise modified.
The TEXT background control characters map to the
CLUT entries, as shown in Table 32.
Table 32 Background CLUT mapping
23.5.8
When set, the attribute takes effect from the current
position until the end of the display window. This is defined
in the MMR Text Area End in single window mode and in
double window mode for Page A, with MMR Text Area
End B for Page B.
CC: The background duration attribute (see Table 35,
bit 8) in combination with the End Of Row attribute
(see Table 35, bit 9) forces the background colour to be
displayed on the row until the end of the text area is
reached.
TXT: This attribute is not available.

The underline attribute causes the characters to have the
bottom scan line of the character cell forced to foreground
colour, including spaces. If background duration is set,
then underline is set until the end of the display window.
CC: The underline attribute (see Table 35, bit 4) is valid
from the time set until the end of row of a display window,
or otherwise modified.
TXT: This attribute is not available.
23.5.10 O
The overline attribute causes the characters to have the
top scan line of the character cell forced to foreground
colour, including spaces. If background duration is set,
then overline is set until the end of the display window.
CC: The overline attribute (see Table 35, bit 5) is valid
from the time set until the end of a row of a display window,
or otherwise modified. Overlining of italic characters is not
possible.
TXT: This attribute is not available.
23.5.11 E
CC: The number of characters in a row is flexible and can
be determined by the end of row attribute (see Table 35,
bit 9). However, the maximum number of character
positions displayed is determined by the setting of the
MMR Text Area Start or Text Area Start B, and MMR Text
Area End or Text Area End B.
Note that, when using the end of row attribute, the next
character location after the attribute should always be
occupied by a ‘space’.
TXT: This attribute is not available, the row length is fixed
at 40 characters.
