- 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).
-
- 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: 0x84)
- ESC E
- Next Line (NEL: 0x85)
- ESC H
- Tab Set (HTS: 0x88)
- ESC M
- Reverse Index (RI: 0x8d)
- ESC N
- Single Shift Select of G2 Character Set (SS2: 0x8e): affects next
- character only
- ESC O
- Single Shift Select of G3 Character Set (SS3: 0x8f): affects next
- character only
- ESC P
- Device Control String (DCS: 0x90)
- ESC V
- Start of Guarded Area (SPA: 0x96)
- ESC W
- End of Guarded Area (EPA: 0x97)
- ESC X
- Start of String (SOS: 0x98)
- ESC Z
- Return Terminal ID (DECID: 0x9a). Obsolete form of CSI c (DA).
- ESC [
- Control Sequence Introducer (CSI: 0x9b)
- ESC \
- String Terminator (ST: 0x9c)
- ESC ]
- Operating System Command (OSC: 0x9d)
- ESC ^
- Privacy Message (PM: 0x9e)
- ESC _
- Application Program Command (APC: 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 and VT320),
- as well as ISO 6429 and aixterm color controls. VT102 features not sup-
- ported are double size characters and blinking characters. 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 discussion of character sets.

- 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)

- 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).

- Ps = 9 1 -> Set foreground color to Red
- Ps = 9 2 -> Set foreground color to Green
- Ps = 9 3 -> Set foreground color to Yellow

- 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 three mutually exclusive modes, each enabled (or disabled) by
- a different parameter in the DECSET (or DECRST) escape sequence. Param-
- eters for all mouse tracking escape sequences generated by xterm encode
- numeric parameters in a single character as value+040. For example, !
- is 1. The screen coodinate system is 1-based.
- X10 compatibility mode sends an escape sequence 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 coordinates of
- the mouse when the button was pressed.
- Normal tracking mode sends an escape sequence on both button press and
- release. Modifier information is also sent. It is enabled by specify-
- ing 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 upper bits encode
- what modifiers were down when the button was pressed and are added
- together. 4=Shift, 8=Meta, 16=Control. Cx and Cy are the x and y coor-
- dinates of the mouse event. The upper left corner is (1,1).
- Mouse hilite 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 hilite 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.

- 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.
