COMMUNICATIONS
Standard
serial communications (RS-232C). The
TELEVIDEO
910 with Retro-Graphics uses XON-

flagging to avoid losing
data
at
high
baud
rates.
GRAPHIC
INPUT
(GIN) When
GIN
is
invoked
on
the 910 Retro-Graphics
terminal, a crosshair cursor appears
on
the screen.
The crosshair can be moved by pressing one
of
the
four cursor movement keys
on
the keyboard. When
the
cursor
is
at
the desired location, the
point
can be
selected by pressing
any
alphanumeric key (other
than
RETURN). This causes the coordinates
of
the
point
to be transmitted back
to
the user program.
TEXT
The
910 Retro-Graphics terminal has continuous
scaling character sizes. Text
can
be
rotated
in 90-
degree increments. One font,
standard
ASCII vector
characters,
is
available.
