Initial import to CVS. Basic functions are working, albeit with a couple of showstopper memory bugs and many missing features. Detaching, reattaching, creating new sessions, listing sessions work acceptably for using with shells. Simple curses programs (top, systat, tetris) and more complicated ones (mutt, emacs) that don't require scrolling regions (ESC[r) mostly work fine (including mutt, emacs). No status bar yet and no key remapping or other customisation.

+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.
