NAME

6       displays - Display Configuration File
7

DESCRIPTION

9       The  interactive  graphics  programs Caesar, Magic, and Gremlin use two
10       separate terminals: a text terminal from which commands are issued, and
11       a  color  graphics  terminal  on  which  graphical output is displayed.
12       These programs use a displays file to  associate  their  text  terminal
13       with its corresponding display device.
14
15       The  displays  file  is  an ASCII text file with one line for each text
16       terminal/graphics terminal pair.  Each line contains 4 items  separated
17       by  spaces:  the name of the port attached to a text terminal, the name
18       of the port attached to the associated graphics terminal, the  phosphor
19       type  of the graphics terminal's monitor, and the type of graphics ter‐
20       minal.
21
22       An applications program may use the phosphor type to select a color map
23       tuned  to the monitor's characteristics.  Only the std phosphor type is
24       supported at UC Berkeley.
25
26       The graphics terminal type specifies the device driver a program should
27       use  when  communicating  with  its  graphics terminal.  Magic supports
28       types UCB512, AED1024, and SUN120.  Other programs may  recognize  dif‐
29       ferent  display types.  See the manual entry for your specific applica‐
30       tion for more information.
31
32       A sample displays file is:
33
34            /dev/ttyi1 /dev/ttyi0 std UCB512
35            /dev/ttyj0 /dev/ttyj1 std UCB512
36            /dev/ttyjf /dev/ttyhf std UCB512
37            /dev/ttyhb /dev/ttyhc std UCB512
38            /dev/ttyhc /dev/ttyhb std UCB512 ®
39
40       In this example, /dev/ttyi1 connects to a text terminal.  An associated
41       UCB512  graphics  terminal  with  standard  phosphor  is  connected  to
42       /dev/ttyi0.

FILES

46       Magic uses the  displays  file  ~cad/lib/displays.   Gremlin  looks  in
47       /usr/local/displays.
