GSX-86 Device Specific Information
ADDS VIEWPOINT WITH DIGITAL ENGINEERING
RETRO-GRAPHICS (GEN. II)
FILENAME
DDGN2B.SYS
DEVICE INDEX
The actual device index for this device is determined
in the ASSIGN.SYS file, which associates a device
index with a GIOS module (device driver).
MAXIMUM BAUD RATE
9600 baud for all graphics
COMMUNICATIONS
Standard serial communications (RS-232C). The
ADDS VIEWPOINT with Retro-Graphics uses
XON-XOFF flagging to avoid losing data at high
baud rates.
GRAPHIC INPUT (GIN)
When GIN is invoked on the VIEWPOINT 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
while simultaneously pressing the SHIFT. 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 VIEWPOINT Retro-Graphics terminal has
continuous scaling character sizes. Text can be
rotated in 90-degree increments. One font, standard
ASCII vector characters, is available.
