+Summary of ANSI standards for ASCII terminals		Joe Smith, 18-May-84
+
+Contents:
+  1.  Overview and Definitions
+  2.  General rules for interpreting an ESCape Sequence
+  3.  General rules for interpreting a Control Sequence
+  4.  C0 and C1 control codes in numeric order
+  5.  Two and three-character ESCape Sequences in numeric order
+  6.  Control Sequences in numeric order
+  7.  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.

+    Control Sequences (defined by ANSI X3.64-1979)
+
+Control Sequences are started by either ESC [ or CSI and are terminated by an
+"alphabetic" character (100 to 176 octal, 40 to 7E hex).  Intermediate
+characters are space through slash (40 to 57 octal, 20 to 2F hex) and parameter
+characters are zero through question mark (60 to 77 octal, 30 to 3F hex,
+including digits and semicolon).  Parameters consist of zero or more decimal
+numbers separated by semicolons.  Leading zeros are optional, leading blanks
+are not allowed.  If no digits precede the final character, the default
+parameter is used.  Many functions treat a parameter of 0 as if it were 1.
