CONSOLE(4)		   Linux Programmer's Manual		    CONSOLE(4)

NAME
       console - console terminal and virtual consoles

DESCRIPTION
       A  Linux	 system	 has up to 63 virtual consoles (character devices with
       major number 4 and minor number 1 to 63), usually called /dev/ttyn with
       1  ≤  n ≤ 63.  The current console is also addressed by /dev/console or
       /dev/tty0, the character device with major number 4 and minor number 0.
       The  device  files /dev/* are usually created using the script MAKEDEV,
       or using mknod(1), usually with mode 0622 and owner root.tty.

       Before kernel version 1.1.54 the number of virtual  consoles  was  com‐
       piled  into  the	 kernel (in tty.h: #define NR_CONSOLES 8) and could be
       changed by editing and recompiling.  Since version 1.1.54 virtual  con‐
       soles are created on the fly, as soon as they are needed.

       Common  ways  to start a process on a console are: (a) tell init(8) (in
       inittab(5)) to start a mingetty(8) (or agetty(8)) on the	 console;  (b)
       ask  openvt(1)  to  start a process on the console; (c) start X—it will
       find the first unused console, and display its output there.  (There is
       also the ancient doshell(8).)

       Common  ways  to	 switch consoles are: (a) use Alt+Fn or Ctrl+Alt+Fn to
       switch to console n; AltGr+Fn might bring you to console n+12 [here Alt
       and  AltGr refer to the left and right Alt keys, respectively]; (b) use
       Alt+RightArrow or Alt+LeftArrow to cycle through	 the  presently	 allo‐
       cated  consoles; (c) use the program chvt(1).  (The key mapping is user
       settable, see loadkeys(1); the above  mentioned	key  combinations  are
       according to the default settings.)

       The command deallocvt(1) (formerly disalloc) will free the memory taken
       by the screen buffers for consoles that no longer have  any  associated
       process.

   Properties
       Consoles	 carry	a  lot	of  state.  I hope to document that some other
       time.  The most important fact is that the consoles simulate vt100 ter‐
       minals.	 In  particular,  a  console  is reset to the initial state by
       printing the two characters ESC c.  All escape sequences can  be	 found
       in console_codes(4).

FILES
       /dev/console
       /dev/tty*
