17 This command is used to display or change the initialization
|
|
|
18 parameters of any SCF-type device such as the video display,
|
|
|
19 printer, RS232 port, etc. A common use is to change baud rates,
|
|
|
20 control key definitions, etc.

|
22 <para>
|
|
|
23 XMODE is very similar to the TMODE command. TMODE only operates on
|
|
|
24 open paths so its effect is temporary. XMODE actually updates the
|
|
|
25 device descriptor so the change persists as long as the computer is
|
|
|
26 running, even if paths to the device are repetitively opened and
|
|
|
27 closed. If XMODE is used to change parameter(s) and the COBBLER
|
|
|
28 program is used to make a new system disk, the changed parameter
|
|
|
29 will be permanently reflected on the new system disk.
|
|
|

|
|
|
31 <para>
|
|
|
32 XMODE requires a device name to be given. If no arguments are
|
|
|
33 given, the present values for each parameter are displayed,
|
|
|
34 otherwise, the parameter(s) given in the argument list are
|
|
|
35 processed. Any number of parameters can be given, and are separated
|
|
|
36 by spaces or commas.
