19.3.7
BACKGROUND COLOUR
CC: This attribute is valid from the time set until end of row
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 the row or until otherwise
modified.
The TEXT background control characters map to the
CLUT entries as shown in Table 19:
Table 19 Background CLUT mapping
19.3.8
BACKGROUND DURATION
The attribute when set takes effect from the current
position until the end of the text display defined in the MMR
Text Area End.
CC: The background duration attribute (see Table 22,
Serial Mode 1, bit 8) in combination with the End Of Row
attribute (see Table 22, Serial Mode 1, bit 9) forces the
background colour to be display on the row until the end of
the text area is reached.
TXT: This attribute is not available.
19.3.9
UNDERLINE
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 text area.
CC: The underline attribute (see Table 22, Serial
Mode 0/1, bit 4) is valid from the time set until end of row
or otherwise modified.
TXT: This attribute is not available.
19.3.10 OVERLINE
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 text area.
CC: The overline attribute (see Table 22, Serial Mode 0/1,
bit 5) is valid from the time set until end of row or otherwise
modified. Overlining of Italic characters is not possible.
TXT: This attribute is not available.
19.3.11 END OF ROW
CC: The number of characters in a row is flexible and can
determined by the end of row attribute (see Table 22 Serial
Mode 1, bit 9). However the maximum number of
character positions displayed is determined by the setting
of the MMR Text Position Horizontal and MMR Text Area
End.
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, row length is fixed at
40 characters.
