here are the VT 100 terminal codes

For those of you interested in the VT100 character codes, here they are.
A few of you sent me private email requests for info about how to embed 
ecs characters in your art, and I will get to that later. But for now, 
the terminal codes:

ANSI/VT2xx/VT102/VT100 Control Codes and Escape Sequences
================================================================================
Set and Reset mode
- all codes are prefixed with ASCII code 27 (escape)
- several codes producse effects similar to DCL commands.  While the immedeate
  effect may be the same, the VAX will not be aware of the terminal changes
  unless you enter the equivalent DCL command.
--------------------------------------------------------------------------------

================================================================================
Character Set Selection
-format for character set selection is <ESC>{primary}{final} where <ESC> is 
 ASCII character 27 (escape).  One character each of {primary} and {final} must
 be included (see below).
--------------------------------------------------------------------------------
   {primary}   Logical Character Set
  ----------- -----------------------
       (                G0
       )                G1
       *                G2    (VT2xx only)
       +                G3    (VT2xx only)

    {final}   Actual Character Set
   --------- ----------------------
       A      U.K. national  (VT100/102 only)
       B      U.S. ASCII
       0      special graphics
       1      alternate character set ROM  (VT100/102 only)
       2      alternate special graphics set ROM  (VT100/102 only)
       <      DEC international  (VT2xx only)
--------------------------------------------------------------------------------
Logical Character Set Selection
-ASCII character 14 selects logical character set G1.  ASCII character 15
 selects logical character set G0 (VT100/102 only).
================================================================================
Character Attributes
-the following attributes remain in effect until turned off explicitly with
 <ESC>[m or <ESC>[0m.
-several codes may be sent at once by placing a semi-colon between the effect
 number, and placing the 'm' at the end of the entire string.  For exampe,
 <ESC>[1;5m would produce highlighted, flashing characters.
-all sequences preceded by ASCII character 27 (escape).
--------------------------------------------------------------------------------
Code Effect             Comments
---- ------------------ --------------------------------------------------------
[m   normal             same as [0m - turns attributes off
[0m  normal             same as [m - turns attributes off
[1m  bold/highlight
[4m  underline          may appear as inverse text on some terminals
[5m  blink
[7m  inverse
--------------------------------------------------------------------------------
Line Attributes
-these sequences effect the chracters on the immedeate line.  Attributes are 
 returned to normal at then end of the line.
-all sequences preceded by ASCII character 27 (escape).
--------------------------------------------------------------------------------
Code Effect                      Comments
---- --------------------------- -----------------------------------------------
#3   double height top half      prints only top half of characters
#4   double height bottom half   prints only bottom half of characters
#5   single width, single height normal characters
#6   double width, single height
================================================================================
Scrolling Region

                <ESC>[t;br
 where:                                    |  Example:
  <ESC> - ASCII character 27 (escape)      |   <ESC>[3;14r would set up a
  t     - top line of scrolling region     |   scrolling region between rows 3
  b     - bottom line of scrolling region  |   and 14 of the terminal screen.
================================================================================
Cursor Movement Commands
-several of these sequences have option counts or cursor positions available.
 n represents a count, while l and c represent line and column numbers re-
 spectively.  Numbers should be placed before the code letter (A, B, D, etc.).
-the cursor position sequence ([l;cH or [l;cf) should not include the semi-
 colon unless both positions are included.  If only one number is specified, it
 is assumed to be l (the line number).
-all sequences preceded with ASCII character 27 (escape).
--------------------------------------------------------------------------------
Code   Effect             Optional Parameters
------ ------------------ ------------------------------------------------------
[A     cursor up          n - number of lines to move cursor up
[B     cursor down        n - number of lines to move cursor down
[C     cursor right       n - number of lines to move cursor right
[D     cursor left        n - number of lines to move cursor left
[H     cursor placement   l - line number
                          c - column number
[f     cursor placement   (see above)

M      reverse index      (cursor up)
E      next line
7      save cursor
8      restore cursor
================================================================================

-these functions effect the line or space the cursor is currently on.
-n represents an optional count (e.g. <ESC>[P deletes once character, while
 <ESC>[3L inserts 3 blank lines).
