Enable Character Blink
Format: 1B
0D
Description:
The
blink
attribute
is
the
only
modifier
that
is
supported
for
the
display
character
positions.
The
attribute
itself
is
not
necessarily
programmed
with
each
new
character
code.
Rather,
each
time
a
new
character
is
received,
the
current
setting
of
the
character
blink
operator
is
adopted
as
the
working
attribute
for
the
new
character.
If
a
new
character
is
received
while
character
blink
is
enabled,
the
new
character
will
blink.
This
makes
it
possible
to
have
a
display
with
both
blinking
and
non
‐
blinking
characters.
The
blink
period
is
one
second
on
and
one
second
off.
All
characters
that
are
blink
enabled,
blink
at
the
same
time.
The
only
way
to
cause
an
existing
character
to
start
or
stop
blinking
is
to
set
up
the
character
blink
operator,
locate
the
cursor
to
the
correct
character,
and
resend
the
individual
character
code.
