XTerm Control Sequences
Edward Moy
University of California, Berkeley
Revised by
Stephen Gildea
X Consortium (1994)

XFree86 Project (1996-2006)
invisible-island.net (2006-2012)
updated for XTerm Patch #289 (2013/02/06)
Definitions
c The literal character c.
C A single (required) character.
Ps A single (usually optional) numeric parameter, composed of one of
more digits.
Pm A multiple numeric parameter composed of any number of single
numeric parameters, separated by ; character(s). Individual val-
ues for the parameters are listed with Ps .
Pt A text parameter composed of printable characters.
C1 (8-Bit) Control Characters
The xterm program recognizes both 8-bit and 7-bit control characters.
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.
The following pairs of 7-bit and 8-bit control characters are equiva-
lent:
ESC D
Index (IND is 0x84).
ESC E
Next Line (NEL is 0x85).
ESC H
Tab Set (HTS is 0x88).
ESC M
Reverse Index (RI is 0x8d).
ESC N
Single Shift Select of G2 Character Set (SS2 is 0x8e). This
affects next character only.
ESC O
Single Shift Select of G3 Character Set (SS3 is 0x8f). This
affects next character only.
ESC P
Device Control String (DCS is 0x90).
ESC V
Start of Guarded Area (SPA is 0x96).
ESC W
End of Guarded Area (EPA is 0x97).
ESC X
Start of String (SOS is 0x98).
ESC Z
Return Terminal ID (DECID is 0x9a). Obsolete form of CSI c (DA).
ESC [
Control Sequence Introducer (CSI is 0x9b).
ESC \
String Terminator (ST is 0x9c).
ESC ]
Operating System Command (OSC is 0x9d).
ESC ^
Privacy Message (PM is 0x9e).
ESC _
Application Program Command (APC is 0x9f).
These control characters are used in the vtXXX emulation.
VT100 Mode
Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals (i.e., VT220, VT320,
VT420, VT510), as well as ISO 6429 and aixterm color controls. The only
VT102 feature not supported is auto-repeat, since the only way X pro-
vides for this will affect all windows. There are additional control
sequences to provide xterm-dependent functions, such as the scrollbar or
window size. Where the function is specified by DEC or ISO 6429, the
code assigned to it is given in parentheses. The escape codes to desig-
nate and invoke character sets are specified by ISO 2022; see that docu-
ment for a discussion of character sets.
Single-character functions
BEL Bell (Ctrl-G).
BS Backspace (Ctrl-H).
CR Carriage Return (Ctrl-M).
ENQ Return Terminal Status (Ctrl-E). Default response is an empty
string, but may be overridden by a resource answerbackString.
FF Form Feed or New Page (NP). Ctrl-L is treated the same as LF.
LF Line Feed or New Line (NL). (LF is Ctrl-J).
SI Shift In (Ctrl-O) -> Switch to Standard Character Set. This
invokes the G0 character set (the default).
SO Shift Out (Ctrl-N) -> Switch to Alternate Character Set. This
invokes the G1 character set.
SP Space.
TAB Horizontal Tab (HT) (Ctrl-I).
VT Vertical Tab (Ctrl-K). This is treated the same as LF.
Controls beginning with ESC
This excludes controls where ESC is part of a 7-bit equivalent to 8-bit
C1 controls, ordered by the final character(s).
ESC SP F 7-bit controls (S7C1T).
ESC SP G 8-bit controls (S8C1T).
ESC SP L Set ANSI conformance level 1 (dpANS X3.134.1).
ESC SP M Set ANSI conformance level 2 (dpANS X3.134.1).
ESC SP N Set ANSI conformance level 3 (dpANS X3.134.1).
ESC # 3 DEC double-height line, top half (DECDHL).
ESC # 4 DEC double-height line, bottom half (DECDHL).
ESC # 5 DEC single-width line (DECSWL).
ESC # 6 DEC double-width line (DECDWL).
ESC # 8 DEC Screen Alignment Test (DECALN).
ESC % @ Select default character set. That is ISO 8859-1 (ISO 2022).
ESC % G Select UTF-8 character set (ISO 2022).
ESC ( C Designate G0 Character Set (ISO 2022, VT100).
Final character C for designating 94-character sets. In this
list, 0 , A and B apply to VT100 and up, the remainder to
VT220 and up:
C = 0 -> DEC Special Character and Line Drawing Set.
C = A -> United Kingdom (UK).
C = B -> United States (USASCII).
C = 4 -> Dutch.
C = C or 5 -> Finnish.
C = R -> French.
C = Q -> French Canadian.
C = K -> German.
C = Y -> Italian.
C = E or 6 -> Norwegian/Danish.
C = Z -> Spanish.
C = H or 7 -> Swedish.
C = = -> Swiss.
ESC ) C Designate G1 Character Set (ISO 2022, VT100).
The same character sets apply as for ESC ( C.
ESC * C Designate G2 Character Set (ISO 2022, VT220).
The same character sets apply as for ESC ( C.
ESC + C Designate G3 Character Set (ISO 2022, VT220).
The same character sets apply as for ESC ( C.
ESC - C Designate G1 Character Set (VT300).
The same character sets apply as for ESC ( C.
ESC . C Designate G2 Character Set (VT300).
The same character sets apply as for ESC ( C.
ESC / C Designate G3 Character Set (VT300).
These work for 96-character sets only.
C = A -> ISO Latin-1 Supplemental.
ESC 6 Back Index (DECBI), VT420 and up.
ESC 7 Save Cursor (DECSC).
ESC 8 Restore Cursor (DECRC).
ESC 9 Forward Index (DECFI), VT420 and up.
ESC = Application Keypad (DECKPAM).
ESC > Normal Keypad (DECKPNM).
ESC F Cursor to lower left corner of screen. This is enabled by the
hpLowerleftBugCompat resource.
ESC c Full Reset (RIS).
ESC l Memory Lock (per HP terminals). Locks memory above the cur-
sor.
ESC m Memory Unlock (per HP terminals).
ESC n Invoke the G2 Character Set as GL (LS2).
ESC o Invoke the G3 Character Set as GL (LS3).
ESC | Invoke the G3 Character Set as GR (LS3R).
ESC } Invoke the G2 Character Set as GR (LS2R).
ESC ~ Invoke the G1 Character Set as GR (LS1R).
Application Program-Control functions
APC Pt ST None. xterm implements no APC functions; Pt is ignored. Pt
need not be printable characters.
Device-Control functions
DCS Ps; Ps| Pt ST
User-Defined Keys (DECUDK). The first parameter:
Ps = 0 -> Clear all UDK definitions before starting
(default).
Ps = 1 -> Erase Below (default).
The second parameter:
Ps = 0 <- Lock the keys (default).
Ps = 1 <- Do not lock.
The third parameter is a ';'-separated list of strings denot-
ing the key-code separated by a '/' from the hex-encoded key
value. The key codes correspond to the DEC function-key codes
(e.g., F6=17).
DCS $ q Pt ST
Request Status String (DECRQSS). The string following the "q"
is one of the following:
" q -> DECSCA
" p -> DECSCL
r -> DECSTBM
m -> SGR
SP q -> DECSCUSR
xterm responds with DCS 1 $ r Pt ST for valid requests,
replacing the Pt with the corresponding CSI string, or DCS 0 $
r Pt ST for invalid requests.
DCS + p Pt ST
Set Termcap/Terminfo Data (xterm, experimental). The string
following the "p" is a name to use for retrieving data from
the terminal database. The data will be used for the "tcap"
keyboard configuration's function- and special-keys, as well
as by the Request Termcap/Terminfo String control.
DCS + q Pt ST
Request Termcap/Terminfo String (xterm, experimental). The
string following the "q" is a list of names encoded in hexa-
decimal (2 digits per character) separated by ; which corre-
spond to termcap or terminfo key names.
Two special features are also recognized, which are not key
names: Co for termcap colors (or colors for terminfo colors),
and TN for termcap name (or name for terminfo name).
xterm responds with DCS 1 + r Pt ST for valid requests, adding
to Pt an = , and the value of the corresponding string that
xterm would send, or DCS 0 + r Pt ST for invalid requests.
The strings are encoded in hexadecimal (2 digits per charac-
ter).

Send Device Attributes (Secondary DA).
Ps = 0 or omitted -> request the terminal's identification
code. The response depends on the decTerminalID resource set-
ting. It should apply only to VT220 and up, but xterm extends
this to VT100.

If 16-color support is compiled, the following apply. Assume
that xterm's resources are set so that the ISO color codes are
the first 8 of a set of 16. Then the aixterm colors are the
bright versions of the ISO colors:
Ps = 9 0 -> Set foreground color to Black.
Ps = 9 1 -> Set foreground color to Red.
Ps = 9 2 -> Set foreground color to Green.
Ps = 9 3 -> Set foreground color to Yellow.

If xterm is compiled with the 16-color support disabled, it
supports the following, from rxvt:
Ps = 1 0 0 -> Set foreground and background color to
default.
Xterm maintains a color palette whose entries are identified
by an index beginning with zero. If 88- or 256-color support
is compiled, the following apply:
o All parameters are decimal integers.
o RGB values range from zero (0) to 255.
o ISO-8613-3 can be interpreted in more than one way; xterm
allows the semicolons in this control to be replaced by
colons (but after the first colon, colons must be used).
These ISO-8613-3 controls are supported:
Ps = 3 8 ; 2 ; Pr ; Pg ; Pb -> Set foreground color to the
closest match in xterm's palette for the given RGB Pr/Pg/Pb.
Ps = 3 8 ; 5 ; Ps -> Set foreground color to the second
Ps.
Ps = 4 8 ; 2 ; Pr ; Pg ; Pb -> Set background color to the
closest match in xterm's palette for the given RGB Pr/Pg/Pb.
Ps = 4 8 ; 5 ; Ps -> Set background color to the second
Ps.
CSI > Ps; Ps m
Set or reset resource-values used by xterm to decide whether
to construct escape sequences holding information about the
modifiers pressed with a given key. The first parameter iden-
tifies the resource to set/reset. The second parameter is the
value to assign to the resource. If the second parameter is
omitted, the resource is reset to its initial value.
Ps = 0 -> modifyKeyboard.
Ps = 1 -> modifyCursorKeys.
Ps = 2 -> modifyFunctionKeys.
Ps = 4 -> modifyOtherKeys.
If no parameters are given, all resources are reset to their
initial values.
CSI Ps n Device Status Report (DSR).
Ps = 5 -> Status Report. Result (``OK'') is
CSI 0 n
Ps = 6 -> Report Cursor Position (CPR) [row;column].
Result is
CSI r ; c R
CSI > Ps n
Disable modifiers which may be enabled via the CSI > Ps; Ps m
sequence. This corresponds to a resource value of "-1", which
cannot be set with the other sequence. The parameter identi-
fies the resource to be disabled:
Ps = 0 -> modifyKeyboard.
Ps = 1 -> modifyCursorKeys.
Ps = 2 -> modifyFunctionKeys.
Ps = 4 -> modifyOtherKeys.
If the parameter is omitted, modifyFunctionKeys is disabled.
When modifyFunctionKeys is disabled, xterm uses the modifier
keys to make an extended sequence of functions rather than
adding a parameter to each function key to denote the modi-
fiers.

CSI Pt ; Pl ; Pb ; Pr ' w
Enable Filter Rectangle (DECEFR), VT420 and up.
Parameters are [top;left;bottom;right].
Defines the coordinates of a filter rectangle and activates
it. Anytime the locator is detected outside of the filter
rectangle, an outside rectangle event is generated and the
rectangle is disabled. Filter rectangles are always treated
as "one-shot" events. Any parameters that are omitted default
to the current locator position. If all parameters are omit-
ted, any locator motion will be reported. DECELR always can-
cels any prevous rectangle definition.
CSI Ps x Request Terminal Parameters (DECREQTPARM).
if Ps is a "0" (default) or "1", and xterm is emulating VT100,
the control sequence elicits a response of the same form whose
parameters describe the terminal:
Ps -> the given Ps incremented by 2.
Pn = 1 <- no parity.
Pn = 1 <- eight bits.
Pn = 1 <- 2 8 transmit 38.4k baud.
Pn = 1 <- 2 8 receive 38.4k baud.
Pn = 1 <- clock multiplier.
Pn = 0 <- STP flags.
CSI Ps * x

CSI Pm ' {
Select Locator Events (DECSLE).
Valid values for the first (and any additional parameters)
are:

(This is default). It also cancels any filter
rectangle.
Ps = 1 -> report button down transitions.
Ps = 2 -> do not report button down transitions.
Ps = 3 -> report button up transitions.
Ps = 4 -> do not report button up transitions.
CSI Pt; Pl; Pb; Pr $ {
Selective Erase Rectangular Area (DECSERA), VT400 and up.
Pt; Pl; Pb; Pr denotes the rectangle.
CSI Ps ' |
Request Locator Position (DECRQLP).
Valid values for the parameter are:
Ps = 0 , 1 or omitted -> transmit a single DECLRP locator
report.
If Locator Reporting has been enabled by a DECELR, xterm will
respond with a DECLRP Locator Report. This report is also
generated on button up and down events if they have been
enabled with a DECSLE, or when the locator is detected outside
of a filter rectangle, if filter rectangles have been enabled
with a DECEFR.
-> CSI Pe ; Pb ; Pr ; Pc ; Pp & w
Parameters are [event;button;row;column;page].
Valid values for the event:
Pe = 0 -> locator unavailable - no other parameters sent.
Pe = 1 -> request - xterm received a DECRQLP.
Pe = 2 -> left button down.
Pe = 3 -> left button up.
Pe = 4 -> middle button down.
Pe = 5 -> middle button up.
Pe = 6 -> right button down.
Pe = 7 -> right button up.
Pe = 8 -> M4 button down.
Pe = 9 -> M4 button up.
Pe = 1 0 -> locator outside filter rectangle.
``button'' parameter is a bitmask indicating which buttons are
pressed:
Pb = 0 <- no buttons down.
Pb & 1 <- right button down.
Pb & 2 <- middle button down.
Pb & 4 <- left button down.
Pb & 8 <- M4 button down.
``row'' and ``column'' parameters are the coordinates of the
locator position in the xterm window, encoded as ASCII deci-
mal.
The ``page'' parameter is not used by xterm, and will be omit-
ted.
CSI Pm ' }

CSI Pm ' ~
Delete Ps Column(s) (default = 1) (DECDC), VT420 and up.
Operating System Controls
OSC Ps ; Pt ST
OSC Ps ; Pt BEL
Set Text Parameters. For colors and font, if Pt is a "?", the
control sequence elicits a response which consists of the con-
trol sequence which would set the corresponding value. The
dtterm control sequences allow you to determine the icon name
and window title.
Ps = 0 -> Change Icon Name and Window Title to Pt.
Ps = 1 -> Change Icon Name to Pt.
Ps = 2 -> Change Window Title to Pt.
Ps = 3 -> Set X property on top-level window. Pt should be
in the form "prop=value", or just "prop" to delete the prop-
erty
Ps = 4 ; c ; spec -> Change Color Number c to the color
specified by spec. This can be a name or RGB specification as
per XParseColor. Any number of c name pairs may be given.
The color numbers correspond to the ANSI colors 0-7, their
bright versions 8-15, and if supported, the remainder of the
88-color or 256-color table.
If a "?" is given rather than a name or RGB specification,
xterm replies with a control sequence of the same form which
can be used to set the corresponding color. Because more than
one pair of color number and specification can be given in one
control sequence, xterm can make more than one reply.
Ps = 5 ; c ; spec -> Change Special Color Number c to the
color specified by spec. This can be a name or RGB specifica-
tion as per XParseColor. Any number of c name pairs may be
given. The special colors can also be set by adding the maxi-
mum number of colors to these codes in an OSC 4 control:
Pc = 0 <- resource colorBD (BOLD).
Pc = 1 <- resource colorUL (UNDERLINE).
Pc = 2 <- resource colorBL (BLINK).
Pc = 3 <- resource colorRV (REVERSE).
The 10 colors (below) which may be set or queried using 1 0
through 1 9 are denoted dynamic colors, since the correspond-
ing control sequences were the first means for setting xterm's
colors dynamically, i.e., after it was started. They are not
the same as the ANSI colors. These controls may be disabled
using the allowColorOps resource. At least one parameter is
expected for Pt. Each successive parameter changes the next
color in the list. The value of Ps tells the starting point
in the list. The colors are specified by name or RGB specifi-
cation as per XParseColor.
If a "?" is given rather than a name or RGB specification,
xterm replies with a control sequence of the same form which
can be used to set the corresponding dynamic color. Because
more than one pair of color number and specification can be
given in one control sequence, xterm can make more than one
reply.
Ps = 1 0 -> Change VT100 text foreground color to Pt.
Ps = 1 1 -> Change VT100 text background color to Pt.
Ps = 1 2 -> Change text cursor color to Pt.

Ps = 1 5 -> Change Tektronix foreground color to Pt.
Ps = 1 6 -> Change Tektronix background color to Pt.
Ps = 1 7 -> Change highlight background color to Pt.
Ps = 1 8 -> Change Tektronix cursor color to Pt.
Ps = 1 9 -> Change highlight foreground color to Pt.
Ps = 4 6 -> Change Log File to Pt. (This is normally dis-
abled by a compile-time option).
Ps = 5 0 -> Set Font to Pt. These controls may be disabled
using the allowFontOps resource. If Pt begins with a "#",
