-.SH NAME
-console_codes \- Linux console escape and control sequences
-.SH DESCRIPTION
-The Linux console implements a large subset of the VT102 and ECMA-48/ISO
-6429/ANSI X3.64 terminal controls, plus certain private-mode sequences
-for changing the color palette, character-set mapping, and so on.
-In the tabular descriptions below, the second column gives ECMA-48 or DEC
-mnemonics (the latter if prefixed with DEC) for the given function.
-Sequences without a mnemonic are neither ECMA-48 nor VT102.
-.LP
-After all the normal output processing has been done, and a
-stream of characters arrives at the console driver for actual
-printing, the first thing that happens is a translation from
-the code used for processing to the code used for printing.
-.LP
-If the console is in UTF-8 mode, then the incoming bytes are
-first assembled into 16-bit Unicode codes.
-Otherwise, each byte is transformed according to the current mapping table
-(which translates it to a Unicode value).
-See the \fBCharacter Sets\fP section below for discussion.
-.LP
-In the normal case, the Unicode value is converted to a font index,
-and this is stored in video memory, so that the corresponding glyph
-(as found in video ROM) appears on the screen.
-Note that the use of Unicode (and the design of the PC hardware)
-allows us to use 512 different glyphs simultaneously.
-.LP
-If the current Unicode value is a control character, or we are
-currently processing an escape sequence, the value will treated
-specially.
-Instead of being turned into a font index and rendered as
-a glyph, it may trigger cursor movement or other control functions.
-See the \fBLinux Console Controls\fP section below for discussion.
-.LP
-It is generally not good practice to hard-wire terminal controls into
-programs.
-Linux supports a
-.BR terminfo (5)
-database of terminal capabilities.
-Rather than emitting console escape sequences by hand, you will almost
-always want to use a terminfo-aware screen library or utility such as
-.BR ncurses (3),
-.BR tput (1),
-or
-.BR reset (1).
-.SS Linux console controls
-This section describes all the control characters and escape sequences
-that invoke special functions (i.e., anything other than writing a
-glyph at the current cursor location) on the Linux console.
-.PP
-.B "Control characters"
-.sp
-A character is a control character if (before transformation
-according to the mapping table) it has one of the 14 codes
-00 (NUL), 07 (BEL), 08 (BS), 09 (HT), 0a (LF), 0b (VT),
-0c (FF), 0d (CR), 0e (SO), 0f (SI), 18 (CAN), 1a (SUB),
-1b (ESC), 7f (DEL).
-One can set a "display control characters" mode (see below),
-and allow 07, 09, 0b, 18, 1a, 7f to be displayed as glyphs.
-On the other hand, in UTF-8 mode all codes 00-1f are regarded
-as control characters, regardless of any "display control characters"
-mode.
-.PP
-If we have a control character, it is acted upon immediately
-and then discarded (even in the middle of an escape sequence)
-and the escape sequence continues with the next character.
-(However, ESC starts a new escape sequence, possibly aborting a previous
-unfinished one, and CAN and SUB abort any escape sequence.)
-The recognized control characters are BEL, BS, HT, LF, VT, FF,
-CR, SO, SI, CAN, SUB, ESC, DEL, CSI.
-They do what one would expect:
-.HP
-BEL (0x07, \fB^G\fP) beeps;
-.HP
-BS (0x08, \fB^H\fP) backspaces one column
-(but not past the beginning of the line);
-.HP
-HT (0x09, \fB^I\fP) goes to the next tab stop or to the end of the line
-if there is no earlier tab stop;
-.HP
-LF (0x0A, \fB^J\fP), VT (0x0B, \fB^K\fP) and
-FF (0x0C, \fB^L\fP) all give a linefeed,
-and if LF/NL (new-line mode) is set also a carriage return;
-.HP
-CR (0x0D, \fB^M\fP) gives a carriage return;
-.HP
-SO (0x0E, \fB^N\fP) activates the G1 character set;
-.HP
-SI (0x0F, \fB^O\fP) activates the G0 character set;
-.HP
-CAN (0x18, \fB^X\fP) and SUB (0x1A, \fB^Z\fP) interrupt escape sequences;
-.HP
-ESC (0x1B, \fB^[\fP) starts an escape sequence;
-.HP
-DEL (0x7F) is ignored;
-.HP
-CSI (0x9B) is equivalent to ESC [.

-.B Linux Console Private CSI Sequences
-.sp
-.\"
-The following sequences are neither ECMA-48 nor native VT102.
-They are native to the Linux console driver.
-Colors are in SGR parameters:
-0 = black, 1 = red, 2 = green, 3 = brown, 4 = blue, 5 = magenta, 6 =
-cyan, 7 = white.
-.TS
-l l.
-ESC [ 1 ; \fIn\fP ] Set color \fIn\fP as the underline color

-ESC [ 12 ; \fIn\fP ] Bring specified console to the front.
-ESC [ 13 ] Unblank the screen.
-ESC [ 14 ; \fIn\fP ] Set the VESA powerdown interval in minutes.
-.TE
-.SS Character sets
-The kernel knows about 4 translations of bytes into console-screen
-symbols.
-The four tables are: a) Latin1 \-> PC,
-b) VT100 graphics \-> PC, c) PC \-> PC, d) user-defined.
-.PP
-There are two character sets, called G0 and G1, and one of them
-is the current character set.
-(Initially G0.)
-Typing \fB^N\fP causes G1 to become current,
-\fB^O\fP causes G0 to become current.
-.PP
-These variables G0 and G1 point at a translation table, and can be
-changed by the user.
-Initially they point at tables a) and b), respectively.
-The sequences ESC ( B and ESC ( 0 and ESC ( U and ESC ( K cause G0 to
-point at translation table a), b), c) and d), respectively.
-The sequences ESC ) B and ESC ) 0 and ESC ) U and ESC ) K cause G1 to
-point at translation table a), b), c) and d), respectively.
-.PP
-The sequence ESC c causes a terminal reset, which is what you want if the
-screen is all garbled.
-The oft-advised "echo ^V^O" will make only G0 current,
-but there is no guarantee that G0 points at table a).
-In some distributions there is a program
-.BR reset (1)
-that just does "echo ^[c".
-If your terminfo entry for the console is correct
-(and has an entry rs1=\\Ec), then "tput reset" will also work.
-.PP
-The user-defined mapping table can be set using
-.BR mapscrn (8).
-The result of the mapping is that if a symbol c is printed, the symbol
-s = map[c] is sent to the video memory.
-The bitmap that corresponds to
-s is found in the character ROM, and can be changed using
-.BR setfont (8).
-.SS Mouse tracking
-The mouse tracking facility is intended to return
-.BR xterm (1)-compatible
-mouse status reports.
-Because the console driver has no way to know
-the device or type of the mouse, these reports are returned in the
-console input stream only when the virtual terminal driver receives
-a mouse update ioctl.
-These ioctls must be generated by a mouse-aware
-user-mode application such as the
-.BR gpm (8)
-daemon.
-.PP
-The mouse tracking escape sequences generated by
-\fBxterm\fP(1) encode numeric parameters in a single character as
-\fIvalue\fP+040.
-For example, \(aq!\(aq is 1.
-The screen coordinate system is 1-based.
-.PP
-The X10 compatibility mode sends an escape sequence on button press
-encoding the location and the mouse button pressed.
-It is enabled by sending ESC [ ? 9 h and disabled with ESC [ ? 9 l.
-On button press, \fBxterm\fP(1) sends
-ESC [ M \fIbxy\fP (6 characters).
-Here \fIb\fP is button\-1,
-and \fIx\fP and \fIy\fP are the x and y coordinates of the mouse
-when the button was pressed.
-This is the same code the kernel also produces.
-.PP
-Normal tracking mode (not implemented in Linux 2.0.24) sends an escape
-sequence on both button press and release.
-Modifier information is also sent.
-It is enabled by sending ESC [ ? 1000 h and disabled with
-ESC [ ? 1000 l.
-On button press or release, \fBxterm\fP(1) sends ESC [ M
-\fIbxy\fP.
-The low two bits of \fIb\fP encode button information:
-0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
-The upper bits encode what modifiers were down when the button was
-pressed and are added together: 4=Shift, 8=Meta, 16=Control.
-Again \fIx\fP and
-\fIy\fP are the x and y coordinates of the mouse event.
-The upper left corner is (1,1).
-.SS Comparisons with other terminals
-Many different terminal types are described, like the Linux console,
-as being "VT100-compatible".
-Here we discuss differences between the
-Linux console and the two most important others, the DEC VT102 and
-.BR xterm (1).

-.PP
-.B Control-character handling

-.HP
-DC1 (0x11, \fB^Q\fP, XON) resumed transmission;
-.HP
-DC3 (0x13, \fB^S\fP, XOFF) caused VT100 to ignore (and stop transmitting)
-all codes except XOFF and XON.
-.LP
-VT100-like DC1/DC3 processing may be enabled by the terminal driver.

-ESC \\ ST String terminator
-ESC * ... Designate G2 character set

-(in VT100 mode) recognizes ESC c, ESC # 8, ESC >, ESC =,
-ESC D, ESC E, ESC H, ESC M, ESC N, ESC O, ESC P ... ESC \\,
-ESC Z (it answers ESC [ ? 1 ; 2 c, "I am a VT100 with
-advanced video option")
-and ESC ^ ... ESC \\ with the same meanings as indicated above.
-It accepts ESC (, ESC ), ESC *, ESC + followed by 0, A, B for
-the DEC special character and line drawing set, UK, and US-ASCII,
-respectively.
-.PP
-The user can configure \fBxterm\fP(1) to respond to VT220-specific
-control sequences, and it will identify itself as a VT52, VT100, and
-up depending on the way it is configured and initialized.
-.PP
-It accepts ESC ] (OSC) for the setting of certain resources.
-In addition to the ECMA-48 string terminator (ST),
-\fBxterm\fP(1) accepts a BEL to terminate an OSC string.

-.B CSI Sequences
-.sp
-Old versions of \fBxterm\fP(1), for example, from X11R5,
-interpret the blink SGR as a bold SGR.
-Later versions which implemented ANSI colors, for example,
-XFree86 3.1.2A in 1995, improved this by allowing
-the blink attribute to be displayed as a color.
-Modern versions of xterm implement blink SGR as blinking text
-and still allow colored text as an alternate rendering of SGRs.
-Stock X11R6 versions did not recognize the color-setting SGRs until
-the X11R6.8 release, which incorporated XFree86 xterm.
-All ECMA-48 CSI sequences recognized by Linux are also recognized by
-.IR xterm ,
-however \fBxterm\fP(1) implements several ECMA-48 and DEC control sequences
-not recognized by Linux.
-.PP
-The \fBxterm\fP(1)
-program recognizes all of the DEC Private Mode sequences listed
-above, but none of the Linux private-mode sequences.
-For discussion of \fBxterm\fP(1)'s
-own private-mode sequences, refer to the
-\fIXterm Control Sequences\fP

-.SH NOTES
-ESC 8 (DECRC) is not able to restore the character set changed with
-ESC %.
-.SH BUGS
-In 2.0.23, CSI is broken, and NUL is not ignored inside
-escape sequences.
-.PP
-Some older kernel versions (after 2.0) interpret 8-bit control
-sequences.
-These "C1 controls" use codes between 128 and 159 to replace
-ESC [, ESC ] and similar two-byte control sequence initiators.
-There are fragments of that in modern kernels (either overlooked or
-broken by changes to support UTF-8),
-but the implementation is incomplete and should be regarded
-as unreliable.
-.PP
-Linux "private mode" sequences do not follow the rules in ECMA-48
-for private mode control sequences.
-In particular, those ending with ] do not use a standard terminating
-character.
-The OSC (set palette) sequence is a greater problem,
-since \fBxterm\fP(1) may interpret this as a control sequence
-which requires a string terminator (ST).
-Unlike the \fBsetterm\fP(1) sequences which will be ignored (since
-they are invalid control sequences), the palette sequence will make
-\fBxterm\fP(1) appear to hang (though pressing the return-key
-will fix that).
-To accommodate applications which have been hardcoded to use Linux
-control sequences,
-set the \fBxterm\fP(1) resource \fBbrokenLinuxOSC\fP to true.
-.PP
-An older version of this document implied that Linux recognizes the
-ECMA-48 control sequence for invisible text.
-It is ignored.
