NAME

       displays - Display Configuration File

DESCRIPTION

       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
       terminal.

       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
       /dev/ttyi0.

FILES

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