6 To use a serial port as console you need to compile the support into your
14 It is possible to specify multiple devices for console output. You can
16 use for console output.
20 console=device,options
22 device: tty0 for the foreground virtual console
23 ttyX for any other virtual console
35 You can specify multiple console= options on the kernel command line.
39 the last device will be used when you open ``/dev/console``.
42 console=ttyS1,9600 console=tty0
44 defines that opening ``/dev/console`` will get you the current foreground
45 virtual console, and kernel messages will appear on both the VGA
46 console and the 2nd serial port (ttyS1 or COM2) at 9600 baud.
53 2. ``/dev/console`` will be associated with the first registered device.
57 This rule is used also when the last console= parameter is not used
64 console=ttyS1,9600 console=tty0 console=tty1
65 console=tty0 console=ttyS1,9600 console=tty1
68 ``/dev/console`` gets associated with ``tty0``. It is because kernel
70 because of the default behavior when no console device is specified,
73 Note that the last ``console=tty1`` parameter still makes a difference.
75 defined ``tty1`` as the login console.
77 If no console device is specified, the first device found capable of
78 acting as a system console will be used. At this time, the system
81 become the console.
83 You will need to create a new device to use ``/dev/console``. The official
84 ``/dev/console`` is now character device 5,1.
86 (You can also use a network device as a console. See
89 Here's an example that will use ``/dev/ttyS1`` (COM2) as the console.
92 1. Create ``/dev/console`` (real console) and ``/dev/tty0`` (master virtual
93 console)::
96 rm -f console tty0
97 mknod -m 622 console c 5 1
109 append = "console=ttyS1,9600"
121 console for the first time, because otherwise init will probably
122 set the baudrate to 38400 (baudrate of the virtual console).
124 6. ``/dev/console`` and X
125 Programs that want to do something with the virtual console usually
126 open ``/dev/console``. If you have created the new ``/dev/console`` device,
127 and your console is NOT the virtual console some programs will fail.
129 ``/dev/console instead of /dev/tty0``. Some of those programs are::
135 Note that if you boot without a ``console=`` option (or with
136 ``console=/dev/tty0``), ``/dev/console`` is the same as ``/dev/tty0``.
