|
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
