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.
