-.SH NAME
-vcs, vcsa \- virtual console memory
-.SH DESCRIPTION
-.I /dev/vcs0
-is a character device with major number 7 and minor number
-0, usually with mode 0644 and ownership root:tty.
-It refers to the memory of the currently
-displayed virtual console terminal.
-.P
-.I /dev/vcs[1\-63]
-are character devices for virtual console
-terminals, they have major number 7 and minor number 1 to 63, usually
-mode 0644 and ownership root:tty.
-.I /dev/vcsa[0\-63]
-are the same, but
-using
-.IR "unsigned short" s
-(in host byte order) that include attributes,
-and prefixed with four bytes giving the screen
-dimensions and cursor position:
-.IR lines ,
-.IR columns ,
-.IR x ,
-.IR y .
-.RI ( x
-=
-.I y
-= 0 at the top left corner of the screen.)
-.P
-When a 512-character font is loaded,
-the 9th bit position can be fetched by applying the
-.BR ioctl (2)
-.B VT_GETHIFONTMASK
-operation
-(available since Linux 2.6.18)
-on
-.IR /dev/tty[1\-63] ;
-the value is returned in the
-.I "unsigned short"
-pointed to by the third
-.BR ioctl (2)
-argument.
-.P
-These devices replace the screendump
-.BR ioctl (2)
-operations of
-.BR ioctl_console (2),
-so the system
-administrator can control access using filesystem permissions.
-.P
-The devices for the first eight virtual consoles may be created by:
-.P
-.in +4n
-.EX
-for x in 0 1 2 3 4 5 6 7 8; do
-    mknod \-m 644 /dev/vcs$x c 7 $x;
-    mknod \-m 644 /dev/vcsa$x c 7 $[$x+128];
-done
-chown root:tty /dev/vcs*
-.EE
-.in
-.P
-No
-.BR ioctl (2)
-requests are supported.

-.SH VERSIONS
-Introduced with Linux 1.1.92.
-.SH EXAMPLES
-You may do a screendump on vt3 by switching to vt1 and typing
-.P
-.in +4n
-.EX
-cat /dev/vcs3 >foo
-.EE
-.in
-.P
-Note that the output does not contain
-newline characters, so some processing may be required, like
-in
-.P
-.in +4n
-.EX
-fold \-w 81 /dev/vcs3 | lpr
-.EE
-.in
-.P
-or (horrors)
-.P
-.in +4n
-.EX
-setterm \-dump 3 \-file /proc/self/fd/1
-.EE
-.in
-.P
-The
-.I /dev/vcsa0
-device is used for Braille support.
-.P
-This program displays the character and screen attributes under the
-cursor of the second virtual console, then changes the background color
-there:
