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): affects
next character only
ESC O
Single Shift Select of G3 Character Set (SS3 is 0x8f): 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), as well as ISO 6429 and aixterm color controls. The only VT102
features not supported is auto-repeat, since the only way X provides 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 designate and invoke
character sets are specified by ISO 2022; see that document for a dis-
cussion 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 answer-
backString.
FF Form Feed or New Page (NP) (Ctrl-L) same as LF
LF Line Feed or New Line (NL) (Ctrl-J)
SO Shift Out (Ctrl-N) -> Switch to Alternate Character Set:
invokes the G1 character set.
SP Space.
TAB Horizontal Tab (HT) (Ctrl-I)
VT Vertical Tab (Ctrl-K) same as LF

invokes the G0 character set (the default).
Controls beginning with ESC (other than those where ESC is part of a
7-bit equivalent to 8-bit C1 controls), ordered by the final charac-
ter(s).
ESC SP F 7-bit controls (S7C1T).
ESC SP G 8-bit controls (S8C1T).

Application Program-Control functions
APC Pt ST 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
denoting 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
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 + q Pt ST Request Termcap/Terminfo String (xterm, experimental).
The string following the "q" is a list of names encoded
in hexadecimal (2 digits per character) separated by ;
which correspond to termcap or terminfo key names.
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 character).
Functions using CSI , ordered by the final character(s)

Initiate highlight mouse tracking. Parameters are
[func;startx;starty;firstrow;lastrow]. See the section
Mouse Tracking.
CSI Ps X Erase Ps Character(s) (default = 1) (ECH)
CSI Ps Z Cursor Backward Tabulation Ps tab stops (default = 1)
(CBT)
CSI Pm ` Character Position Absolute [column] (default = [row,1])
(HPA)
CSI Ps b Repeat the preceding graphic character Ps times (REP)
CSI Ps c Send Device Attributes (Primary DA)
Ps = 0 or omitted -> request attributes from terminal.
The response depends on the decTerminalID resource set-
ting.
-> CSI ? 1 ; 2 c (``VT100 with Advanced Video
Option'')
-> CSI ? 1 ; 0 c (``VT101 with No Options'')
-> CSI ? 6 c (``VT102'')
-> CSI ? 6 0 ; 1 ; 2 ; 6 ; 8 ; 9 ; 1 5 ; c (``VT220'')
The VT100-style response parameters do not mean anything
by themselves. VT220 parameters do, telling the host
what features the terminal supports:
-> 1 132-columns
-> 2 Printer
-> 6 Selective erase
-> 8 User-defined keys
-> 9 National replacement character sets
-> 1 5 Technical characters
-> 2 2 ANSI color, e.g., VT525
-> 2 9 ANSI text locator (i.e., DEC Locator mode)
CSI > Ps c Send Device Attributes (Secondary DA)
Ps = 0 or omitted -> request the terminal's identifi-
cation code. The response depends on the decTerminalID
resource setting. It should apply only to VT220 and up,
but xterm extends this to VT100.
-> CSI > Pp ; Pv ; Pc c
where Pp denotes the terminal type
-> 0 (``VT100'')
-> 1 (``VT220'')
and Pv is the firmware version (for xterm, this is the
XFree86 patch number, starting with 95). In a DEC termi-
nal, Pc indicates the ROM cartridge registration number
and is always zero.

CSI Pt ; Pl ; Pb ; Pr ' w
Enable Filter Rectangle (DECEFR)
Parameters are [top;left;bottom;right].
Defines the coordinates of a filter rectangle and acti-
vates 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 omitted, any locator motion will be
reported. DECELR always cancels 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.
1 -> no parity

CSI Ps x Select Attribute Change Extent (DECSACE).
Ps = 0 -> from start to end position, wrapped
Ps = 1 -> from start to end position, wrapped
Ps = 2 -> rectangle (exact).
CSI Pc; Pt; Pl; Pb; Pr$ x
Fill Rectangular Area (DECFRA).
Pc is the character to use.
Pt; Pl; Pb; Pr denotes the rectangle.
CSI Ps ; Pu ' z
Enable Locator Reporting (DECELR)
Valid values for the first parameter:
Ps = 0 -> Locator disabled (default)
Ps = 1 -> Locator enabled
Ps = 2 -> Locator enabled for one report, then dis-
abled
The second parameter specifies the coordinate unit for
locator reports.
Valid values for the second parameter:
Pu = 0 or omitted -> default to character cells
Pu = 1 -> device physical pixels
Pu = 2 -> character cells
CSI Pt; Pl; Pb; Pr$ z
Erase Rectangular Area (DECERA).
Pt; Pl; Pb; Pr denotes the rectangle.
CSI Pm ' { Select Locator Events (DECSLE)
Valid values for the first (and any additional parame-
ters) are:
Ps = 0 -> only respond to explicit host requests
(DECRQLP)
(default) 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).
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 loca-
tor 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 rectan-
gles 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 but-
tons 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 decimal.
The ``page'' parameter is not used by xterm, and will be
omitted.
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 con-
sists of the control sequence which would set the corre-
sponding 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 property
Ps = 4 ; c ; spec -> Change Color Number c to the
color specified by spec, i.e., a name or RGB specifica-
tion as per XParseColor. Any number of c name pairs may
be given. The color numbers correspond to the ANSI col-
ors 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 specifica-
tion, 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 specifica-
tion can be given in one control sequence, xterm can make
more than one reply.
The 8 colors which may be set using 1 0 through 1 7 are
denoted dynamic colors, since the corresponding 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. One or more parameters is
expected for Pt. Each successive parameter changes the
next color in the list. The value of Ps tells the start-
ing point in the list. The colors are specified by name
or RGB specification as per XParseColor.
If a "?" is given rather than a name or RGB specifica-
tion, 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 3 -> Change mouse foreground color to Pt
Ps = 1 4 -> Change mouse background 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 color to Pt
Ps = 1 8 -> Change Tektronix cursor color to Pt
Ps = 4 6 -> Change Log File to Pt (normally disabled
by a compile-time option)
Ps = 5 0 -> Set Font to Pt If Pt begins with a "#",
index in the font menu, relative (if the next character
is a plus or minus sign) or absolute. A number is
expected but not required after the sign (the default is
the current entry for relative, zero for absolute index-
ing).
Ps = 5 1 (reserved for Emacs shell)
Ps = 5 2 -> Manipulate Selection Data. These controls
may be disabled using the allowWindowOps resource. The
parameter Pt is parsed as
Pc; Pd
The first, Pc, may contain any character from the set c
p s 0 1 2 3 4 5 6 7 . It is used to construct a
list of selection parameters for clipboard, primary,
select, or cut buffers 0 through 8 respectively, in the
order given. If the parameter is empty, xterm uses s 0 ,
to specify the configurable primary/clipboard selection
and cut buffer 0.
The second parameter, Pd, gives the selection data. Nor-
mally this is a string encoded in base64. The data
becomes the new selection, which is then available for
pasting by other applications.
If the second parameter is a ? , xterm replies to the
host with the selection data encoded using the same pro-
tocol.

PC-Style Function Keys
If xterm does minimal translation of the function keys, it usually does
this with a PC-style keyboard, so PC-style function keys result. Sun
keyboards are similar to PC keyboards. Both have cursor and scrolling
operations printed on the keypad, which duplicate the smaller cursor and
scrolling keypads.
X does not predefine NumLock (used for VT220 keyboards) or Alt (used as
an extension for the Sun/PC keyboards) as modifiers. These keys are
recognized as modifiers when enabled by the numLock resource, or by the
DECSET 1 0 3 5 control sequence.
The cursor keys transmit the following escape sequences depending on the
mode specified via the DECCKM escape sequence.
Key Normal Application
--------------------------------------
Cursor Up CSI A SS3 A
Cursor Down CSI B SS3 B
Cursor Right CSI C SS3 C
Cursor Left CSI D SS3 D
--------------------------------------
The home- and end-keys (unlike PageUp and other keys also on the 6-key
editing keypad) are considered "cursor keys" by xterm. Their mode is
also controlled by the DECCKM escape sequence:
Key Normal Application
----------------------------------
Home CSI H SS3 H
End CSI F SS3 F
----------------------------------
The application keypad transmits the following escape sequences depend-
ing on the mode specified via the DECPNM and DECPAM escape sequences.
Use the NumLock key to override the application mode.
Not all keys are present on the Sun/PC keypad (e.g., PF1, Tab), but are
supported by the program.

Older versions of xterm implement different escape sequences for F1
through F4. These can be activated by setting the oldXtermFKeys
resource. However, since they do not correspond to any hardware termi-
nal, they have been deprecated. (The DEC VT220 reserves F1 through F5
for local functions such as Setup).

In normal mode, i.e., a Sun/PC keyboard when the sunKeyboard resource is
false, xterm recognizes function key modifiers which are parameters
appended before the final character of the control sequence.
Code Modifiers
---------------------------------
2 Shift
3 Alt
4 Shift + Alt
5 Control
6 Shift + Control
7 Alt + Control
8 Shift + Alt + Control
---------------------------------
For example, shift-F5 would be sent as CSI 1 5 ; 2 ~
If the alwaysUseMods resource is set, the Meta modifier also is recog-
nized, making parameters 9 through 16.
VT220-Style Function Keys
However, xterm is most useful as a DEC VT102 or VT220 emulator. Set the
sunKeyboard resource to true to force a Sun/PC keyboard to act like a
VT220 keyboard.
The VT102/VT220 application keypad transmits unique escape sequences in
application mode, which are distinct from the cursor and scrolling key-
pad:

The VT220 provides a 6-key editing keypad, which is analogous to that on
the PC keyboard. It is not affected by DECCKM or DECPNM/DECPAM:
Key Normal Application
----------------------------------

Delete CSI 3 ~ CSI 3 ~
Home CSI 1 ~ CSI 1 ~
End CSI 4 ~ CSI 4 ~

The VT220 provides 8 additional function keys. With a Sun/PC keyboard,
access these keys by Control/F1 for F13, etc.

Sun-Style Function Keys
The xterm program provides support for Sun keyboards more directly, by a
menu toggle that causes it to send Sun-style function key codes rather
than VT220. Note, however, that the sun and VT100 emulations are not
really compatible. For example, their wrap-margin behavior differs.
Only function keys are altered; keypad and cursor keys are the same.
The emulation responds identically. See the xterm-sun terminfo entry
for details.
HP-Style Function Keys
Similarly, xterm can be compiled to support HP keyboards. See the
xterm-hp terminfo entry for details.
The Alternate Screen Buffer
Xterm maintains two screen buffers. The normal screen buffer allows you
to scroll back to view saved lines of output up to the maximum set by
the saveLines resource. The alternate screen buffer is exactly as large
as the display, contains no additional saved lines. When the alternate
screen buffer is active, you cannot scroll back to view saved lines.
Xterm provides control sequences and menu entries for switching between
the two.
Most full-screen applications use terminfo or termcap to obtain strings
used to start/stop full-screen mode, i.e., smcup and rmcup for terminfo,
or the corresponding ti and te for termcap. The titeInhibit resource
removes the ti and te strings from the TERMCAP string which is set in
the environment for some platforms. That is not done when xterm is
built with terminfo libraries because terminfo does not provide the
whole text of the termcap data in one piece. It would not work for ter-
minfo anyway, since terminfo data is not passed in environment vari-
ables; setting an environment variable in this manner would have no
effect on the application's ability to switch between normal and alter-
nate screen buffers. Instead, the newer private mode controls (such as
1 0 4 9 ) for switching between normal and alternate screen buffers sim-
ply disable the switching. They add other features such as clearing the
display for the same reason: to make the details of switching indepen-
dent of the application that requests the switch.
Bracketed Paste Mode
When bracketed paste mode is set, pasted text is bracketed with control
sequences so that the program can differentiate pasted text from typed-
in text. When bracketed paste mode is set, the program will receive:
ESC [ 200 ~, followed by the pasted text, followed by ESC [ 201 ~.
Mouse Tracking
The VT widget can be set to send the mouse position and other informa-
tion on button presses. These modes are typically used by editors and
other full-screen applications that want to make use of the mouse.
There are six mutually exclusive modes. One is DEC Locator mode,
enabled by the DECELR CSI Ps ; Ps ' z control sequence, and is not
described here (control sequences are summarized above). The remaining
five modes are each enabled (or disabled) by a different parameter in
DECSET CSI ? Pm h or DECRST CSI ? Pm l control sequence.
Manifest constants for the parameter values are defined in xcharmouse.h
as follows:
#define SET_X10_MOUSE 9
#define SET_VT200_MOUSE 1000
#define SET_VT200_HIGHLIGHT_MOUSE 1001
#define SET_BTN_EVENT_MOUSE 1002
#define SET_ANY_EVENT_MOUSE 1003
The motion reporting modes are strictly xterm extensions, and are not
part of any standard, though they are analogous to the DEC VT200 DECELR
locator reports.
Parameters (such as pointer position and button number) for all mouse
tracking escape sequences generated by xterm encode numeric parameters
in a single character as value+32. For example, ! specifies the value
1. The upper left character position on the terminal is denoted as 1,1.
X10 compatibility mode sends an escape sequence only on button press,
encoding the location and the mouse button pressed. It is enabled by
specifying parameter 9 to DECSET. On button press, xterm sends CSI M
CbCxCy (6 characters). Cb is button-1. Cx and Cy are the x and y coor-
dinates of the mouse when the button was pressed.
Normal tracking mode sends an escape sequence on both button press and
release. Modifier key (shift, ctrl, meta) information is also sent. It
is enabled by specifying parameter 1000 to DECSET. On button press or
release, xterm sends CSI M CbCxCy. The low two bits of Cb encode button
information: 0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
The next three bits encode the modifiers which were down when the button
was pressed and are added together: 4=Shift, 8=Meta, 16=Control. Note
however that the shift and control bits are normally unavailable because
xterm uses the control modifier with mouse for popup menus, and the
shift modifier is used in the default translations for button events.
The Meta modifier recognized by xterm is the mod1 mask, and is not nec-
essarily the "Meta" key (see xmodmap). Cx and Cy are the x and y coor-
dinates of the mouse event, encoded as in X10 mode.
Wheel mice may return buttons 4 and 5. Those buttons are represented by
the same event codes as buttons 1 and 2 respectively, except that 64 is
added to the event code. Release events for the wheel buttons are not
reported.
Mouse highlight tracking notifies a program of a button press, receives
a range of lines from the program, highlights the region covered by the
mouse within that range until button release, and then sends the program
the release coordinates. It is enabled by specifying parameter 1001 to
DECSET. Highlighting is performed only for button 1, though other but-
ton events can be received. Warning: use of this mode requires a coop-
erating program or it will hang xterm. On button press, the same infor-
mation as for normal tracking is generated; xterm then waits for the
program to send mouse tracking information. All X events are ignored
until the proper escape sequence is received from the pty: CSI Ps ; Ps ;
Ps ; Ps ; Ps T . The parameters are func, startx, starty, firstrow, and
lastrow. func is non-zero to initiate highlight tracking and zero to
abort. startx and starty give the starting x and y location for the
highlighted region. The ending location tracks the mouse, but will
never be above row firstrow and will always be above row lastrow. (The
top of the screen is row 1.) When the button is released, xterm reports
the ending position one of two ways: if the start and end coordinates
are valid text locations: CSI t CxCy. If either coordinate is past the
end of the line: CSI T CxCyCxCyCxCy. The parameters are startx, starty,
endx, endy, mousex, and mousey. startx, starty, endx, and endy give the
starting and ending character positions of the region. mousex and
mousey give the location of the mouse at button up, which may not be
over a character.
Button-event tracking is essentially the same as normal tracking, but
xterm also reports button-motion events. Motion events are reported
only if the mouse pointer has moved to a different character cell. It
is enabled by specifying parameter 1002 to DECSET. On button press or
release, xterm sends the same codes used by normal tracking mode. On
button-motion events, xterm adds 32 to the event code (the third charac-
ter, Cb). The other bits of the event code specify button and modifier
keys as in normal mode. For example, motion into cell x,y with button 1
down is reported as CSI M @ CxCy. ( @ = 32 + 0 (button 1) + 32 (motion
indicator) ). Similarly, motion with button 3 down is reported as CSI M
B CxCy. ( B = 32 + 2 (button 3) + 32 (motion indicator) ).
Any-event mode is the same as button-event mode, except that all motion
events are reported, even if no mouse button is down. It is enabled by
specifying 1003 to DECSET.
Tektronix 4014 Mode
Most of these sequences are standard Tektronix 4014 control sequences.
Graph mode supports the 12-bit addressing of the Tektronix 4014. The
major features missing are the write-through and defocused modes. This
document does not describe the commands used in the various Tektronix
plotting modes but does describe the commands to switch modes.
