Serial Console
|
|
##############
|
|
|
|
For the average user a serial console has no advantage over a console offered
|
|
by a directly attached keyboard and screen. Serial consoles are much slower,
|
|
taking up to a second to fill a 80 column by 24 line screen. Serial consoles
|
|
generally only support non-proportional ASCII text, with limited support for
|
|
languages other than English.
|
|
|
|
There are some scenarios where serial consoles are useful. System administration
|
|
of remote computers is usually done using :ref:`ssh`, but there are times when
|
|
access to the console is the only way to diagnose and correct software failures.
|
|
Major upgrades to the installed distribution may also require console access.
|
|
|

|
|

|
|
|
|
.. cfgcmd:: set system console device <device> speed <speed>
|
|
|
|
The speed (baudrate) of the console device. Supported values are:
