.SH NAME

|
.SH 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
|
|
.B displays
|
|
file to associate their text terminal with its corresponding display device.
|
|
.PP
|
|
The
|
|
.B 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.
|
|
.PP
|
|
An applications program may use the phosphor type
|
|
to select a color map tuned to the monitor's characteristics.
|
|
Only the \fBstd\fR phosphor type is supported at UC Berkeley.
|
|
.PP
|
|
The graphics terminal type specifies the device driver
|
|
a program should use when communicating with its graphics terminal.
|
|
Magic supports types \fBUCB512\fR, \fBAED1024\fR, and \fBSUN120\fR.
|
|
Other programs may recognize different display types.
|
|
See the manual entry for your specific application for more information.

A sample displays file is:
|
|
.sp
|
|
.in +0.5i
|
|
.B
|
|
.br
|
|
/dev/ttyi1 /dev/ttyi0 std UCB512
|
|
.br
|
|
/dev/ttyj0 /dev/ttyj1 std UCB512
|
|
.br
|
|
/dev/ttyjf /dev/ttyhf std UCB512
|
|
.br
|
|
/dev/ttyhb /dev/ttyhc std UCB512
|
|
.br
|
|
/dev/ttyhc /dev/ttyhb std UCB512
|
|
.R
|
|
.in -0.5i
|
|
.br
|
|
.PP
|
|
In this example, \fB/dev/ttyi1\fR connects to a text terminal.
|
|
An associated \fBUCB512\fR graphics terminal with
|
|
standard phosphor is connected to \fB/dev/ttyi0\fR.
|
|
|
|
.SH "FILES"
|
|
Magic uses the displays file ~cad/lib/displays.
|
|
Gremlin looks in /usr/local/displays.
