CSI modes¶
Status: Standard (ANSI modes), DEC (private modes), xterm and Extension for the numbers above 1000.
Modes are persistent terminal switches. They stay in effect until reset,
until a terminal reset (RIS, DECSTR) changes them, or until the PTY
session ends.
Syntax¶
CSI Pm h SM: set one or more ANSI modes
CSI Pm l RM: reset one or more ANSI modes
CSI ? Pm h DECSET: set one or more DEC private modes
CSI ? Pm l DECRST: reset one or more DEC private modes
CSI Ps $ p DECRQM: query an ANSI mode
CSI ? Ps $ p DECRQM: query a private mode
The ? selects a separate namespace; ANSI mode 4 (insert) and private mode
?4 (smooth scroll) are unrelated. Multiple parameters are set in order:
CSI ? 1000 ; 1006 h
Applications should tolerate terminals that honor only part of a combined request, and should never combine a mode whose failure is harmful with others.
DECRQM replies¶
CSI ? Ps ; Pm $ y
Pm |
Meaning |
|---|---|
0 |
Mode not recognized |
1 |
Set |
2 |
Reset |
3 |
Permanently set |
4 |
Permanently reset |
The ANSI form is the same without the private marker: CSI Ps $ p asks about
ANSI mode Ps and is answered CSI Ps ; Pm $ y. A reply must use the marker of the
request and echo its mode number exactly. Revenant's regression checks requests
through 65535, the range its backend accepts for this parameter; within that range an
unknown mode is answered with Pm = 0, never mapped onto a smaller mode. A terminal
that stores the number in 15 bits answers 32793 (25 + 32768) with DECTCEM's state,
which is a wrong answer, not an unknown one.
DECRQM is the safest feature-detection tool for modes: a terminal that does not implement DECRQM at all sends nothing, so a timeout is still required. Some terminals answer only the private form. See Queries.
just probe csi-decrqm mode-queries sends both forms for known modes around their
set and reset controls (IRM and DECTCEM, restored afterwards), for an unknown mode,
and for 32767, 32768, 32772/32793 and 65535, and grades each reply on marker, echoed
number and status separately; a timeout is shown as unknown. Its scope is those
requests: one exact reply shows that request was answered, not that any other mode
is supported.
ANSI modes¶
| Mode | Name | Effect |
|---|---|---|
2 |
KAM | Keyboard action: lock the keyboard; rarely implemented |
4 |
IRM | Insert mode; printing shifts the rest of the row right |
12 |
SRM | Send/receive: reset means local echo; almost never implemented |
20 |
LNM | Line feed/new line: LF also performs CR |
DEC private modes¶
Screen and cursor¶
| Mode | Name | Effect | Status |
|---|---|---|---|
?1 |
DECCKM | Application cursor keys: arrows send SS3 A instead of CSI A |
DEC |
?2 |
DECANM | VT52 mode when reset; do not use | DEC |
?3 |
DECCOLM | 132 columns when set; also clears the screen unless ?40 is reset |
DEC |
?4 |
DECSCLM | Smooth scroll; ignored by most emulators | DEC |
?5 |
DECSCNM | Reverse video for the whole screen | DEC |
?6 |
DECOM | Origin mode: cursor addressing is relative to the scrolling region | DEC |
?7 |
DECAWM | Autowrap; reset means text overwrites the last column | DEC |
?8 |
DECARM | Autorepeat | DEC |
?12 |
Cursor blink | xterm (att610) | |
?25 |
DECTCEM | Cursor visible | DEC |
?40 |
Allow ?3 to resize |
xterm | |
?45 |
Reverse wraparound | xterm | |
?47 |
Alternate screen (no cursor save) | xterm | |
?66 |
DECNKM | Application keypad | DEC |
?67 |
DECBKM | Backspace sends BS rather than DEL | DEC |
?69 |
DECLRMM | Enable left/right margins | DEC |
?80 |
DECSDM | Sixel display mode; polarity is disputed, see Sixel | Disputed |
?1047 |
Alternate screen; clears it on return | xterm | |
?1048 |
Save/restore cursor as DECSC/DECRC | xterm | |
?1049 |
Save cursor, switch to alternate screen, clear it; reverse on reset | xterm |
Window Ops: xterm applies its ColumnMode permission to the
80/132-column switching controls (?3 and ?40), in addition to c132.
This label applies to those controls, not every mode on this page. See
Window Ops policy.
?1049 is what full-screen programs use. The alternate screen has no
scrollback, and emulators that enable ?1007 translate wheel events to
arrow keys there.

Terminals impose a timeout (typically 1 s) after which they render anyway,
so a crashed application cannot freeze the display. Terminfo announces it
with the Sync user capability. Implemented by Contour, kitty, WezTerm,
Ghostty, foot, Alacritty, iTerm2, VTE, Windows Terminal, xterm.js, and
relayed by tmux 3.4+; not by xterm, PuTTY, or Apple Terminal.
Ownership and cleanup¶
A mode belongs to the terminal session, not to a process. The terminal cannot tell which nested program enabled it, so full-screen applications must reset the modes they enable, including on error paths and signal handlers.
Cleanup is not restoration. Resetting a mode chooses its reset state; it
does not recover an unknown value that another application selected
earlier. DECRQM before enabling, and restoring the answered state after,
is the only correct sequence; few programs do it.
XTSAVE / XTRESTORE (CSI ? Pm s, CSI ? Pm r) save and restore
private modes in xterm and several others, but with ?69 set CSI Pm s
means DECSLRM. The Kitty keyboard protocol solved the same problem with an
explicit stack; see Kitty keyboard.
Reset¶
ESC c RIS: hard reset; clears the screen and every mode
CSI ! p DECSTR: soft reset; modes to defaults, screen preserved
reset(1) sends RIS plus terminfo rs1–rs3. Emulators differ on whether
RIS clears scrollback, the title stack, and private colors.
