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) + + .. note:: If you use a USB to serial converter please note that most of them + use software emulation without flow control, thus you should start with a + common baud rate of 9600 as otherwise you could get |
