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>'
Defines the specified device as a system console. Available console devices
can be (see completion helper):
* ``ttySN`` - Serial device name
* ``ttyUSBX`` - USB Serial device name
* ``hvc0`` - Xen console
.. cfgcmd:: set system console device '<device>' speed '<speed>'
The speed (baudrate) of the console device. Supported values are:
* ``1200`` - 1200 bps
* ``2400`` - 2400 bps
* ``4800`` - 4800 bps
* ``9600`` - 9600 bps
* ``19200`` - 19,200 bps
* ``38400`` - 38,400 bps (default for Xen console)
* ``57600`` - 57,600 bps
* ``115200`` - 115,200 bps (default for serial console)

Network Console
##############
TBD.
.. cfgcmd:: set system console network '<netconXX>'
... and many more commands ...
