displays - Display Configuration File
The interactive graphics programs Caesar, Magic, and Gremlin use two
separate terminals: a text terminal from which commands are issued, and
a color graphics terminal on which graphical output is displayed.
These programs use a displays file to associate their text terminal
with its corresponding display device.
The displays file is an ASCII text file with one line for each text
terminal/graphics terminal pair. Each line contains 4 items separated
by spaces: the name of the port attached to a text terminal, the name
of the port attached to the associated graphics terminal, the phosphor
type of the graphics terminal's monitor, and the type of graphics
An applications program may use the phosphor type to select a color map
tuned to the monitor's characteristics. Only the std phosphor type is
supported at UC Berkeley.
The graphics terminal type specifies the device driver a program should
use when communicating with its graphics terminal. Magic supports
types UCB512, AED1024, and SUN120. Other programs may recognize
different display types. See the manual entry for your specific
application for more information.
A sample displays file is:
/dev/ttyi1 /dev/ttyi0 std UCB512
/dev/ttyj0 /dev/ttyj1 std UCB512
/dev/ttyjf /dev/ttyhf std UCB512
/dev/ttyhb /dev/ttyhc std UCB512
/dev/ttyhc /dev/ttyhb std UCB512 (R)
In this example, /dev/ttyi1 connects to a text terminal. An associated
UCB512 graphics terminal with standard phosphor is connected to
Magic uses the displays file ~cad/lib/displays. Gremlin looks in
