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 ®

       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.
