///1DEVICE
Syntax:
DEVICE { NAMES | VALUES | physical-dev | logical-dev}
DEVICE logical-dev=physical-dev {option}
{,physical-dev {option},...}
DEVICE logical-dev = NULL
DEVICE physical-dev {option}
DEVICE CONSOLE [ PAGE | COLUMNS = columns | LINES = lines]
Explanation:
DEVICE displays current logical device assignments and physical
device names. DEVICE assigns logical devices to peripheral
devices attached to the computer. DEVICE also sets the
communications protocol and speed of a peripheral device, and
displays or sets the current console screen size.
///2Options
[ XON | NOXON | baud-rate ]
XON refers to the XON/XOFF communications protocol.
NOXON indicates no protocol and the computer sends data to
the device whether or not the device is ready to
receive it.
baud-rate is the speed of the device. The system
accepts the following baud rates:
50 75 110 134
150 300 600 1200
1800 2400 3600 4800
7200 9600 19200
///2Examples
A>DEVICE
Displays the physical devices and current assignments of
the logical devices in the system.
A>DEVICE NAMES
Lists the physical devices with a summary of the device
characteristics.
A>DEVICE VALUES
Displays the current logical device assignments.
A>DEVICE CRT
Displays the attributes of the physical device CRT.
A>DEVICE CON
Displays the assignment of the logical device CON:
A>DEVICE CONOUT:=LPT,CRT
Assigns the system console output (CONOUT:) to the
printer (LPT) and the screen (CRT).
A>DEVICE AUXIN:=CRT2 [XON,9600]
Assigns the auxiliary logical input device (AUXIN:) to
the physical device CRT using protocol XON/XOFF and
sets the transmission rate for the device at 9600.
A>DEVICE LST:=NULL
Disconnects the list output logical device (LST:).
A>DEVICE LPT [XON,9600]
Sets the XON/XOFF protocol for the physical device LPT
and sets the transmission speed at 9600.
A>DEVICE CONSOLE [PAGE]
Displays the current console page width in columns and
length in lines.
A>DEVICE CONSOLE [COLUMNS=40 LINES=16]
Sets the screen size to 40 columns and 16 lines.
