TITLE: ANSI commands of which ANSI.SYS is a subset: ANSI Standard (X3.64) Control Sequences for Video Terminals and Peripherals in alphabetic order by mnemonic (Inspired by the article "Toward Stardardized Video Terminals: ANSI X3.64 Device Control" by Mark L. Siegel, April 1984 BYTE, page 365) (Ps and Pn are parameters expressed in ASCII.) (Numeric parameters are given in decimal radix.) (Abbreviations are explained in detail at end.)

This is too complicated to explain fully here, so read Jim Fleming's article in the February 1983 BYTE, especially pages 214 through 224. Fe is a Final character of a 2-character Escape sequence that has an equivalent representation in an 8-bit environment as a Ce-type (Fe ranges from 4/0 to 5/15) Fs is a Final character of a 2-character Escape sequence that is standardized internationally with identical representation in 7-bit and 8-bit environments and is independent of the currently designated C0 and C1 control sets (Fs ranges from 6/0 to 7/14) I is an Intermediate character from 2/0 to 2/15 (inclusive) in the ASCII table P is a parameter character from 3/0 to 3/15 (inclusive) in the ASCII table Pn is a numeric parameter in a control sequence, a string of zero or more characters ranging from 3/0 to 3/9 in the ASCII table Ps is a variable number of selective parameters in a control sequence with each selective parameter separated from the other by the code 3/11 (which usually represents a semicolon); Ps ranges from 3/0 to 3/9 and includes 3/11 v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v Format Effectors versus Editor Functions A format effector specifies how the final output is to be created. An editor function allows you to modify the specification. For instance, a format effector that moves the "active position" (the cursor or equvalent) one space to the left would be useful when you want to create an overstrike, a compound character made of two standard characters overlaid. Control-H, the Backspace character, is actually supposed to be a format effector, so you can do this. But many systems use it in a nonstandard fashion, as an editor function, deleting the character to the left of the cursor and moving the cursor left. When Control-H is assumed to be an editor function, you cannot predict whether its use will create an overstrike unless you also know whether the output device is in an "insert mode" or an "overwrite mode". When Control-H is used as a format effector, its effect can always be predicted. The familiar characters carriage return, linefeed, formfeed, etc., are defined as format effectors. v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v ^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^ ANSI X3.64 Mode-Changing Parameters for use with the Select Mode (SM) and Reset Mode (RM) functions Parameter Mode Mode Function Characters Mnemonic column/ graphic row repres. ---------------------------------------------------------------------------- 3/0 0 an error condition 3/1 1 GATM guarded-area transfer mode 3/2 2 KAM keyboard action mode 3/3 3 CRM control representation mode 3/4 4 IRM insertion/replacement mode 3/5 5 SRTM status-reporting transfer mode 3/6 6 ERM erasure mode 3/7 7 VEM vertical editing mode 3/8 8 reserved for future standardization 3/9 9 reserved for future standardization 3/10 : reserved separator for parameters 3/11 ; Standard separator for parameters 3/12 < reserved for private (experimental) use 3/13 = reserved for private (experimental) use 3/14 > reserved for private (experimental) use 3/15 ? reserved for private (experimental) use 3/1 3/0 10 HEM horizontal editing mode 3/1 3/1 11 PUM positioning unit mode 3/1 3/2 12 SRM send/receive mode 3/1 3/3 13 FEAM format effector action mode 3/1 3/4 14 FETM format effector transfer mode 3/1 3/5 15 MATM multiple area transfer mode 3/1 3/6 16 TTM transfer termination mode 3/1 3/7 17 SATM selected area transfer mode 3/1 3/8 18 TSM tabulation stop mode 3/1 3/9 19 EBM editing boundary mode 3/1 3/10 1: reserved separator for parameters 3/1 3/11 1; Standard separator for parameters 3/1 3/12 1< error condition--unspecified recovery 3/1 3/13 1= error condition--unspecified recovery 3/1 3/14 1> error condition--unspecified recovery 3/1 3/15 1? error condition--unspecified recovery 3/2 3/0 20 LNM linefeed/newline mode (not in ISO 6429) 3/2 3/1 21 . . . . reserved for future standardization . . 3/9 3/9 99 3/12 3/0 <0 . . . . reserved for private (experimental) use . . 3/15 3/15 ?? v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v ^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^ NOTES ON THE DEC VT100 IMPLEMENTATION In the case of the popular DEC VT100 video-terminal implementation, the only mode that may be altered is the linefeed/newline (LNM) mode. Other modes are considered permanently set, reset, or not applicable .More.. as follows: Set: ERM Reset: CRM, EBM, FEAM, FETM, IRM, KAM, PUM, SRTM, TSM N/A: GATM, HEM, MATM, SATM, TTM, VEM Control sequences implemented in the VT100 are as follows: CPR, CUB, CUD, CUF, CUP, CUU, DA, DSR, ED, EL, HTS, HVP, IND, LNM, NEL, RI, RIS, RM, SGR, SM, TBC plus several private DEC commands. Erasing parts of the display (EL and ED) in the VT100 is performed thus: Erase from cursor to end of line Esc [ 0 K or Esc [ K Erase from beginning of line to cursor Esc [ 1 K Erase line containing cursor Esc [ 2 K Erase from cursor to end of screen Esc [ 0 J or Esc [ J Erase from beginning of screen to cursor Esc [ 1 J Erase entire screen Esc [ 2 J The VT100 responds to receiving the DA (Device Attributes) control Esc [ c (or Esc [ 0 c) by transmitting the sequence Esc [ ? l ; Ps c where Ps is a character that describes installed options. The VT100's cursor location can be read with the DSR (Device Status Report) control Esc [ 6 n The VT100 reports by transmitting the CPR sequence Esc [ Pl ; Pc R where Pl is the line number and Pc is the column number (in decimal). v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v ^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^ The complete document describing the standard, "ANSI X3.64-1979: Additional Controls for Use with the American National Standard Code for Information Interchange," can be ordered for $13.50 (plus $4 postage) from Standards Sales Department American National Standards Institute 1430 Broadway New York, NY 10018 212/354-3300 It's best to read the full standard before using it. It also helps to have copies of the related standards "X3.4-1977: American National Standard Code for Information Interchange" (the ASCII standard) and "X3.41.1974: Code-Extension Techniques for Use with the 7-Bit Coded Character Set of American National Standard for Information Interchange." See also the chapter "Using Extended Screens and Keyboard Control" in the IBM PC-DOS manuals (versions 2.0, 2.1, and 3.0), especially for the coding for character attributes.
