displays - Display Configuration File
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 phos-
phor 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 applica-
tion 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
Magic uses the displays file ~cad/lib/displays. Gremlin looks in /usr/local/displays.

iscc - serial communications interface
controller iscc0 at isa0
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)).
On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is
available for use by application programs as an additional communications port.
In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.
Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as
the serial system console. The iscc terminal driver enforces this restriction.
No modem control is supported for either the CON or AUX serial communications ports.
