All +other control characters cause no action to be taken. + + Control characters (codes 00 - 037 inclusive) are specifically excluded +from the control sequence syntax, but may be embedded within a control +sequence. Embedded control characters are executed as soon as they are +encountered by the VT100. The processing of the control sequence then +continues with the next character recieved. The exceptions are: if the <ESC> +character occurs, the current control sequence is aborted, and a new one +commences beginning with the <ESC> just recieved. If the character <CAN> +(030) or the character <SUB> (032) occurs, the current control sequence is +aborted. The ability to embed control characters allows the synchronization +characters XON and XOFF to be interpreted properly without affecting the +control sequence. + + + +Control Octal +Character Code Action Taken +------------------------------------------------------------------------------ +<NUL> 0000 Ignored on input; not stored in buffer +<ENQ> 0005 Transmit ANSWERBACK message +<BEL> 0007 Sound bell +<BS> 0010 Move cursor to the left one position, unless it is at + the left margin, in which case no action is taken. +<HT> 0011 Move cursor to the next tab stop, or to the right + margin if no further tabs are set. +<LF> 0012 Causes either a line feed or new line operation (See + new line mode.) +<VT> 0013 Same as <LF>. +<FF> 0014 Same as <LF>. +<CR> 0015 Move the cursor to the left margin of the current line. +<SO> 0016 Invoke the G1 character set, as designated by the SCS + control sequence. +<SI> 0017 Invoke the G0 character set, as selected by the <ESC>( + sequence. +<DC1> 0021 Causes terminal to resume transmission (XON). +<DC3> 0023 Causes terminal to stop transmitting all codes except + XOFF and XON (XOFF). +<CAN> 0030 If sent during a control sequence, the sequence id + immediately terminated and not executed.

The American National Standards Institute has since +standardized escape and control sequences in terminals in documents X3.41-1974 +and X3.64-1977. + + The VT100 is compatible with both the previous Digital standard and +ANSI standards. Customers may use existing Digital software designed around +the VT52 or new VT100 software. The VT100 has a "VT52 compatible" mode in +which the VT100 responds to control sequences like a VT52. In this mode, most +of the new VT100 features cannot be used. + + Throughout this document references will be made to "VT52 mode" or +"ANSI mode". These two terms are used to indicate the VT100's software +compatibility. + + +NOTE: The ANSI standards allow the manufacturer flexibility in implementing +each function. This document describes how the VT100 will respond to the +implemented ANSI central function. + +NOTE: ANSI standards may be obtained by writing: + + American National Standards Institute + Sales Department + 1430 Broadway + New York, NY, 10018 + + + +Definitions +----------- + + Control Sequence Introducer (CSI) - An escape sequence that provides + supplementary controls and is itself a prefix affecting the + interpretation of a limited number of contiguous characters. + In the VT100, the CSI is: <ESC>[ + + Parameter: (1) A string of zero or more decimal characters which + represent a single value. Leading zeros are ignored. The + decimal characters have a range of 0 (060) to 9 (071). + (2) The value so represented. + + Numeric Parameter: A parameter that represents a number, designated by + Pn. + + Selective Parameter: A parameter that selects a subfunction from a + specified set of subfunctions, designated by Ps. In general, a + control sequence with more than one selective parameter causes + the same effect as several control sequences, each with one + selective parameter, e.g., CSI Psa; Psb; Psc F is identical to + CSI Psa F CSI Psb F CSI Psc F. + + Parameter String: A string of parameters separated by a semicolon. + + Default: A function-dependent value that is assumed when no explicit + value, or a value of 0, is specified. + + Final character: A character whose bit combination terminates an + escape or control sequence. + + + EXAMPLE: Control sequence to turn off all character attributes, then + turn on underscore and blink attributes (SGR). <ESC>[0;4;5m + + Sequence: + + + Delimiters + / \ + / \ + | | + \ / \ / + <ESC>[ 0 ; 4 ; 5 m + ^^^^^^ ^ ^ ^ ^ + |||||| | | | | + \||||/ \ | / +------Final character + \||/ \ | / + CSI Selective + Parameters + + + The octal representation of this string is: + + 033 0133 060 073 064 073 065 0155 + <ESC> [ 0 ; 4 ; 5 m + + + Alternate sequences which will accomplish the same thing: + + 1) <ESC>[;4;m + + 2) <ESC>[m + <ESC>[4m + <ESC>[5m + + 3) <ESC>[0;04;005m + + +Control Sequences +----------------- + + All of the following control sequences are transmitted from the Host to +VT100 unless otherwise noted. All of the control sequences are a subset of +those defined in ANSI X 3.64 1977 and ANSI X 3.41 1974. + + The following text conforms to these formatting conventions: + + 1) Control characters are designated by angle brackets (e.g. + the Escape character is <ESC>). + + 2) Parameters are indicated by curly braces. + + 3) Parameter types usually are indicated as one of: + + {Pn} A string of digits representing a numerical + value. + + {Ps} A character that selects an item from a list. + + {a-z} Any lowercase sequence of one44 or more + characters in braces represent a value to be + entered (as in {Pn}), and the name in the + braces will be referred to in explanatory text. + + 4) Spaces in the control sequence are present for clarity and + may be omitted. Spaces which are required will be + surrounded by single quotes: ' '. + + 5) All other characters are literals. + + + + + +CPR Cursor Position Report VT100 to Host + + <ESC>[ {Pn} ; {Pn} R Default Value: 1 + + The CPR sequence reports the active position by means of the + parameters. This sequence has two parameter values, the first + specifying the line and the second specifying the column. The default + condition with no parameters present, or parameters of 0, is equivelent + to a cursor at home position. + + The numbering of the lines depends upon the state of the Origin Mode + (DECOM). + + This control sequence is sent in reply to a device status report (DSR) + command sent from the host. + + + +CUB Cursor Backward Host to VT100 & VT100 to Host + + <ESC>[ {Pn} D Default Value: 1 + + The CUB sequence move the cursor to the left. The distance moved is + determined by the parameter. If the parameter missing, zero, or one, + the cursor is moved one position. The cursor cannot be moved past the + left margin. Editor Function. + + +CUD Cursor Down Host to VT100 & VT100 to Host + + <ESC>[ {Pn} B Default value: 1 + + Moves the cursor down a number of lines as specified in the parameter + without changing columns. The cursor cannot be moved past the bottom + margin. Editor Function. + + +CUF Cursor Foreward Host to VT100 & VT100 to Host + + <ESC>[ {Pn} C Default Value: 1 + + The CUF sequence moves the cursor to the right a number of positions + specified in the parameter. The cursor cannot be moved past the right + margin. Editor Function. + + +CUP Cursor Position + + <ESC>[ {Pn} ; {Pn} H Default Value: 1 + + The CUP sequence moves the curor to the position specified by the + parameters. The first parameter specifies the line, and the second + specifies the column. A value of zero for either line or column moves + the cursor to the first line or column in the display. The default + string (<ESC>H) homes the cursor. In the VT100, this command behaves + identically to it's format effector counterpart, HVP. + + The numbering of the lines depends upon the state of the Origin Mode + (DECOM). Editor Function. + + +CUU Cursor Up Host to VT100 & VT100 to Host + + <ESC>[ {Pn} A Default Value: 1 + + Moves the cursor up without changing columns. The cursor is moved up a + number of lines as indicated by the parameter. The cursor cannot be + moved beyond the top margin. Editor Function. + + +DA Device Attributes Host to VT100 & VT100 to Host + + <ESC>[ {Pn} c Default Value: 0 + + 1) The host requests the VT100 to send a DA sequence to indentify + itself. This is done by sending the DA sequence with no parameters, + or with a parameter of zero. + + 2) Response to the request described above (VT100 to host) is generated + by the VT100 as a DA control sequencewith the numeric parameters as + follows: + + Option Present Sequence Sent + --------------------------------------------- + No options <ESC>[?1;0c + Processor Option (STP) <ESC>[?1;1c + Advanced Video Option (AVO) <ESC>[?1;2c + AVO and STP <ESC>[?1;3c + Graphics Option (GPO) <ESC>[?1;4c + GPO and STP <ESC>[?1;5c + GPO and AVO <ESC>[?1;6c + GPO, ACO, and STP <ESC>[?1;7c + +<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>, +<<<I doubt if alot of these DEC commands work..a few do..

The + reset state causes only VT52 compatible escape sequences to be + recognized. The set state causes only ANSI compatible escape sequences + to be recognized. See the entries for MODES, SM, and RM. + + +DECARM Auto Repeat Mode (DEC Private) + + This is a private parameter to the SM and RM control sequences. The + reset state causes no keyboard keys to auto-repeat, the set state + causes most of them to. See MODES, SM, and RM. + + +DECAWM Autowrap Mode (DEC Private) + + This is a private parameter to the SM and RM control sequences. The + reset state prevents the cursor from moving when characters are + recieved while at the right margin. The set state causes these + characters to advance to the next line, causing a scroll up if required + and permitted. See MODES, SM, and RM. + + +DECCKM Cursor Keys Mode (DEC Private) + + This is a private parameter to the SM and RM control requences. This + mode is only effective when the terminal is in keypad application mode + (DECPAM) and the ANSI/VT52 mode (DECANM) is set. Under these + conditions, if this mode is reset, the cursor keys will send ANSI + cursor control commands. If setm the cursor keys will send application + function commands (See MODES, RM, and SM). + + +DECCOLM Column Mode (DEC Private) + + This is a private parameter to the SM and RM control sequences. The + reset state causes an 80 column screen to be used. The set state + causes a 132 column screen to be used. See MODES, RM, and SM. + + +DECDHL Double Height Line (DEC Private) + + Top Half: <ESC>#3 + Bottom Half: <ESC>#4 + + These sequences cause the line containing the cursor to become the top + or bottom half of a double-height, double width line. The sequences + should be used in pairs on adjacent lines with each line containing the + same character string. If the line was single width single height, all + characters to the right of the center of the screen will be lost. The + cursor remains over the same character position, unless it would be to + the right of the right margin, in which case it is moved to the right + margin. + + +DECDWL Double Width Line (DEC Private) + + <ESC>#6 + + This causes the line that contains the cursor to become double-width + single height. If the line was single width, all characters ro the + right of the center of the screen will be lost. The cursor remains + over the same character position, unless it would be to the right of + the right margin, in which case it is moved to the right margin. + + +DECID Identify Terminal (DEC Private) + + <ESC>Z + + This sequence causes the same response as the DA sequence. This + sequence will not be supported in future models. + + +DECINLM Interlace Mode (DEC Private) + + This is a private parameter to the RM and SM control sequences. The + reset state (non-interlace) causes the video processor to display 240 + scan lines per frame. The set state causes the video processor to + display 480 scan lines per screen. See MODES, RM, and SM. + + +DECKPAM Keypad Application Mode (DEC Private) + + <ESC>= + + The auxiliary keypad keys will transmit control sequences. + + +DECKPNM Keypad Numeric Mode (DEC Private) + + <ESC> > + + The auxiliary keypad keys will send ASCII codes corresponding to the + characters engraved on their keys. + + +DECLL Load LEDs (DEC Private) + + <ESC>[ {Ps} q Default Value: 0 + + Load the four programmable LEDs on the keyboard according to the + prameter(s). + + Parameter Meaning + ----------------------- + 0 Clear All LEDs + 1 Light L1 + 2 Light L2 + 3 Light L3 + 4 Light L4 + + +DECOM Origin Mode (DEC Private) + + This is a private parameter to SM and RM control sequences. The reset + state causes the origin (or home position) to be the upper left + character position of the screen. Line and column numbers are, + therefore, independent of current margin settings. The cursor may be + positioned outside the margins with a cursor position (CUP) or + horizontal and vertical position (HVP) control. + + The set state causes the origin to be at the upper left character + position within the current margins. Line and column numbers are, + therefore, relative to the current margin settings. The cursor cannot + be positioned outside of the margins. + + The cursor is moved to the new home position when this mode is set or + reset. Lines and columns are numbered consecutively, with the origin + being line 1, column 1. + + +DECRC Restore Cursor (DEC Private) + + <ESC>8 + + This sequence causes the previously saved cursor position, graphic + rendition, and character set to be restored. + + +DECREPTPARM Report Terminal Parameters VT100 to Host + + <ESC>[ {sol} ; {par} ; {nbits} ; {xspd} ; {rspd} ; {cmul} ; {flags} x + + This sequence is generated by the VT100 to notify the host of the + status of selected terminal parameters.

If 0, the terminal will be + allowed to send unsolicited DECREPTPARMs. These reports will be + generated each time the terminal exits the SET-UP mode. If {Ps} is 1, + then the terminal will only generate DECREPTPARMs in response to a + request. + + +DECSC Save Cursor (DEC Private) + + <ESC>7 + + Causes the cursor position, graphic rendition, and character set to be + saved. (See DECRC) + + +DECSCLM Scrolling Mode (DEC Private) + + This is a private parameter to RM and SM control sequences. The reset + state causes scrolls to "jump" instantaneuously one line at a time. + The set state causes the scrolls to be "smooth", and scrolls at a + maximum rate of siz lines/sec. See MODES, RM, and SM. + + +DECSCNM Screen Mode (DEC Private) + + This is a private parameter to RM and SM control sequences. The reset + state causes the screen to be black with white characters; the set + state causes the screen to be white with black characters. See MODES, + RM, and SM. + +<<<<This one works...and is very handy! >>>> +DECSTBM Set Top and Bottom Margins (DEC Private) + + <ESC>[ {Pn} ; {Pn} r Default Values: See Below + + This sequence sets the top and bottom margins to define the scrolling + region. The first parameter is the line number of the first line in + the scrolling region; the second parameter is the line number of the + bottom line of the scrolling region. Default is the entire screen (no + margins). The minimum region allowed is two lines, i.e., the top line + must be less than the bottom. The cursor is placed in the home + position (See DECOM). + + +DECSWL Single-width Line (DEC Private) + + <ESC>#5 + + This causes the line which contains the cursor to become single-width, + single-height.
