VT100 emulation requirements + +The VT100 USER GUIDE and ANSI standard X3.64-1979 both list the ANSI ESCape +sequences in alphabetic order by mnemonic, but do not have a have a cross +reference in order by ASCII code. This paper lists the combination of all +definitions from the three ANSI standards in numeric order. For a description +of the advantages of using these standards, see the article "Toward +Standardized Video Terminals" in the April-1984 issue of BYTE magazine. + +ANSI X3.4-1977 defines the 7-bit ASCII character set (C0 and G0). It was +written in 1968, revised in 1977, and explains the decisions made in laying out +the ASCII code. In particular, it explains why ANSI chose to make ASCII +incompatible with EBCDIC in order to make it self-consistant. + +ANSI X3.41-1974 introduces the idea of an 8-bit ASCII character set (C1 and G1 +in addition to the existing C0 and G0). It describes how to use the 8-bit +features in a 7-bit environment. X3.41 defines the format of all ESCape +sequences, but defines only the 3-character ones with a parameter character +in the middle. These instruct the terminal how to interpret the C0, G0, C1, +and G1 characters (such as by selecting different character-set ROMs). + + Note: NAPLPS does videotex graphics by redefining the C1 set and + selecting alternate G0, G1, G2, and G3 sets. + See the February 1983 issue of BYTE magazine for details. + +ANSI X3.64-1979 defines the remaining ESCape sequences. It defines all the C1 +control characters, and specifies that certain two-character ESCape sequences +in the 7-bit environment are to act exactly like the 8-bit C1 control set. +X3.64 introduces the idea of a Control-Sequence, which starts with CSI +character, has an indefinite length, and is terminated by an alphabetic +character. The VT100 was one of the first terminals to implement this +standard. + +Definitions: + + Control Character - A single character with an ASCII code with the range + of 000 to 037 and 200 to 237 octal, 00 to 1F and 80 to 9F hex. + + Escape Sequence - A two or three character string staring with ESCape. + (Four or more character strings are allowed but not defined.) + + Control Sequence - A string starting with CSI (233 octal, 9B hex) or + with ESCape Left-Bracket, and terminated by an alphabetic character. + Any number of parameter characters (digits 0 to 9, semicolon, and + question mark) may appear within the Control Sequence. The terminating + character may be preceded by an intermediate character (such as space). + Character classifications: + +C0 Control 000-037 octal, 00-1F hex (G0 is 041-176 octal, 21-7E hex) +SPACE 040+240 octal, 20+A0 hex Always and everywhere a blank space +Intermediate 040-057 octal, 20-2F hex !"#$%&'()*+,-./ +Parameters 060-077 octal, 30-3F hex 0123456789:;<=>? +Uppercase 100-137 octal, 40-5F hex @ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_ +Lowercase 140-176 octal, 60-7E hex `abcdefghijlkmnopqrstuvwxyz{|}~ +Alphabetic 100-176 octal, 40-7E hex (all of upper and lower case) +Delete 177 octal, 7F hex Always and everywhere ignored +C1 Control 200-237 octal, 80-9F hex 32 additional control characters +G1 Displayable 241-376 octal, A1-FE hex 94 additional displayable characters +Special 240+377 octal, A0+FF hex Same as SPACE and DELETE + +Note that in this paper, the terms uppercase, lowercase, and alphabetics +include more characters than just A to Z. + +------------------------------------------------------------------------------ + +General rules for interpreting an ESCape Sequence: + + An ESCape Sequence starts with the ESC character (033 octal, 1B hex). +The length of the ESCape Sequence depends on the character that immediately +follows the ESCape. + +If the next character is + C0 control: Interpret it first, then resume processing ESCape sequence. + Example: CR, LF, XON, and XOFF work as normal within an ESCape sequence. + Intermediate: Expect zero or more intermediates, a parameter terminates + a private function, an alphabetic terminates a standard sequence. + Example: ESC ( A defines standard character set, ESC ( 0 a DEC set. + Parameter: End of a private 2-character escape sequence. + Example: ESC = sets special keypad mode, ESC > clears it. + Uppercase: Translate it into a C1 control character and act on it. + Example: ESC D does indexes down, ESC M indexes up. (CSI is special) + Lowercase: End of a standard 2-character escape sequence. + Example: ESC c resets the terminal. + Delete: Ignore it, and continue interpreting the ESCape sequence + C1 and G1: Treat the same as their 7-bit counterparts + + Note that CSI is the two-character sequence ESCape left-bracket or the 8-bit +C1 code of 233 octal, 9B hex. CSI introduces a Control Sequence, which +continues until an alphabetic character is received. + +General rules for interpreting a Control Sequence: + +1) It starts with CSI, the Control Sequence Introducer. +2) It contains any number of parameter characters (0123456789:;<=>?). +3) It terminates with an alphabetic character. +4) Intermediate characters (if any) immediately precede the terminator. + +If the first character after CSI is one of "<=>?" (074-077 octal, 3C-3F hex), +then Control Sequence is to be interpreted according to private standards (such +as setting and resetting modes not defined by ANSI). The terminal should +expect any number of numeric parameters, separated by semicolons (073 octal, +3B hex). Only after the terminating alphabetic character is received should +the terminal act on the Control Sequence. + +============================================================================= + C0 set of 7-bit control characters (from ANSI X3.4-1977). + +Oct Hex Name * (* marks function used in DEC VT series or LA series terminals) +--- -- - --- - -------------------------------------------------------------- +000 00 @ NUL * Null filler, terminal should ignore this character +001 01 A SOH Start of Header +002 02 B STX Start of Text, implied end of header +003 03 C ETX End of Text, causes some terminal to respond with ACK or NAK +004 04 D EOT End of Transmission +005 05 E ENQ * Enquiry, causes terminal to send ANSWER-BACK ID +006 06 F ACK Acknowledge, usually sent by terminal in response to ETX +007 07 G BEL * Bell, triggers the bell, buzzer, or beeper on the terminal +010 08 H BS * Backspace, can be used to define overstruck characters +011 09 I HT * Horizontal Tabulation, move to next predetermined position +012 0A J LF * Linefeed, move to same position on next line (see also NL) +013 0B K VT * Vertical Tabulation, move to next predetermined line +014 0C L FF * Form Feed, move to next form or page +015 0D M CR * Carriage Return, move to first character of current line +016 0E N SO * Shift Out, switch to G1 (other half of character set) +017 0F O SI * Shift In, switch to G0 (normal half of character set) +020 10 P DLE Data Link Escape, interpret next control character specially +021 11 Q XON * (DC1) Terminal is allowed to resume transmitting +022 12 R DC2 Device Control 2, causes ASR-33 to activate paper-tape reader +023 13 S XOFF* (DC2) Terminal must pause and refrain from transmitting +024 14 T DC4 Device Control 4, causes ASR-33 to deactivate paper-tape reader +025 15 U NAK Negative Acknowledge, used sometimes with ETX and ACK +026 16 V SYN Synchronous Idle, used to maintain timing in Sync communication +027 17 W ETB End of Transmission block +030 18 X CAN * Cancel (makes VT100 abort current escape sequence if any) +031 19 Y EM End of Medium +032 1A Z SUB * Substitute (VT100 uses this to display parity errors) +033 1B [ ESC * Prefix to an ESCape sequence +034 1C \ FS File Separator +035 1D ] GS Group Separator +036 1E ^ RS * Record Separator (sent by VT132 in block-transfer mode) +037 1F _ US Unit Separator + +040 20 SP * Space (should never be defined to be otherwise) +177 7F DEL * Delete, should be ignored by terminal + +============================================================================== + C1 set of 8-bit control characters (from ANSI X3.64-1979) + +Oct Hex Name * (* marks function used in DEC VT series or LA series terminals) +--- -- - --- - -------------------------------------------------------------- +200 80 @ Reserved for future standardization +201 81 A Reserved +202 82 B Reserved +203 83 C Reserved +204 84 D IND * Index, moves down one line same column regardless of NL +205 85 E NEL * NEw Line, moves done one line and to first column (CR+LF) +206 86 F SSA Start of Selected Area to be sent to auxiliary output device +207 87 G ESA End of Selected Area to be sent to auxiliary output device +210 88 H HTS * Horizontal Tabulation Set at current position +211 89 I HTJ Hor Tab Justify, moves string to next tab position +212 8A J VTS Vertical Tabulation Set at current line +213 8B K PLD Partial Line Down (subscript) +214 8C L PLU Partial Line Up (superscript) +215 8D M RI * Reverse Index, go up one line, reverse scroll if necessary +216 8E N SS2 * Single Shift to G2 +217 8F O SS3 * Single Shift to G3 (VT100 uses this for sending PF keys) +220 90 P DCS * Device Control String, terminated by ST (VT125 enters graphics) +221 91 Q PU1 Private Use 1 +222 92 R PU2 Private Use 2 +223 93 S STS Set Transmit State +224 94 T CCH Cancel CHaracter, ignore previous character +225 95 U MW Message Waiting, turns on an indicator on the terminal +226 96 V SPA Start of Protected Area +227 97 W EPA End of Protected Area +230 98 X Reserved for for future standard +231 99 Y Reserved +232 9A Z * Reserved, but causes DEC terminals to respond with DA codes +233 9B [ CSI * Control Sequence Introducer (described in a seperate table) +234 9C \ ST * String Terminator (VT125 exits graphics) +235 9D ] OSC Operating System Command (reprograms intelligent terminal) +236 9E ^ PM Privacy Message (password verification), terminated by ST +237 9F _ APC Application Program Command (to word processor), term by ST + +============================================================================== + Character set selection sequences (from ANSI X3.41-1974) + All are 3 characters long (including the ESCape).
