7.4.3.5 Cursor & Flash
A cursor facility may be emulated under software
control, using the “flash” attribute. This allows to
have a “flash-on-word” in serial mode or a “flash-
on-character” in extended parallel mode.
The cursor facility first requires activating the
“flash on” row control bit (refer to Section 7.4.7.3),
which acts as a general flash enable.
Then program the characters with Flashing Char-
acter attribute(s) (serial or extended parallel) at the
required locations.
The flash effect is obtained by toggling the general
flash enable bit.
Several flashing words or characters per screen
can easily be implemented.
7.4.3.6 Italic mode
The italics attribute is a serial attribute; this means
that Italic mode is available in serial mode only.
In the matrix description that follows, line 1 is at the
top of the character, line 13 (or line 26) is at the
bottom.
The codes (seen as spaces) needed to activate
and deactivate the Italic attribute provide a con-
venient method for solving border problems be-
tween italic and non-italic characters.
