D.4.3. Set Character Attributes
A
set attribute is valid until another is set,
or the screen is re-in-
itialized.
TV950:
<ESC> <'G'> <n>
ADM3A:
<Ctrl-E> <n>
or
<ESC> <'%'> <n>
Only
the least significant 4 bits of <n> are evaluated,
their meanings
are:
Bit
0
1
2
3
Vertical line right of character
blinking characters
inverse characters
characters underlined
Example:
<ESC> <'G'> <'0'>
<ESC> <'G'> <'4'>
<ESC> <'G'> <'<'>
No attributes
Inverse characters
Blinking inverse characters
It
must
be noted that the TeleVideo terminal treats
attributes
in
a
different manner. Setting an attribute on the TV950 causes a space being
written
on the screen at the cursor position,
and the remainder of the
screen
is
displayed
using the attribute until
another
attribute
is
encountered or up to the end of the screen.
Due to organizational
rea-
sons,
only
the characters written after setting an attribute are
dis-
played
with
the
attribute,
instead of the entire
remaining
screen.
Additionally, no space is written with the MZ-3500 implementation.
