GSX-86 Device Specific Information
K-4
LEAR SIEGLER ADM5 WITH DIGITAL ENGINEERING
RETRO-GRAPHICS (GEN.II)
FILENAME
DDGN2A.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
LSI ADM5 with Retro-Graphics uses XON-XOFF
flagging to avoid losing data at high baud rates.
GRAPHIC INPUT (GIN)
When GIN is invoked on the ADM5 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 ADM5 Retro-Graphics terminal has continu-
ous scaling character sizes. Text can be rotated in
90-degree increments. One font, standard ASCII
vector characters, is available.
