+       character descriptions has come to  light,  which  identifies  them  as
+       VT100 special characters.
+
+       The DEC Special Character and Line Drawing Set (VT100) is indexed by an
+       ASCII character in the range 96 (`) to 126 (~).  That  index  character
+       is  part  of  the  definition  for  the curses <STRONG>ACS_</STRONG> symbols.  The VT100
+       special characters can be categorized in three groups:
+
+       <STRONG>o</STRONG>   useful graphic symbols with a  standard  <STRONG>ACS_</STRONG>  symbol,  (e.g.,  the
+           line-drawing symbols),
+
+       <STRONG>o</STRONG>   possibly useful characters (these non-standard symbols),
+
+       <STRONG>o</STRONG>   representations  of  control characters (e.g., newline and vertical
+           tabulation).
+
+       A few <STRONG>ACS_</STRONG> symbols do not  fit  into  DEC's  VT100  scheme.   The  AT&amp;T
+       Teletype  5410v1  arrow  symbols  and <STRONG>ACS_BLOCK</STRONG> use indices outside the
+       range 96 to 126.  Two of the  Teletype  symbols  use  indices  in  that
+       range, with different meaning versus the VT100:
+
+       <STRONG>o</STRONG>   <STRONG>ACS_BOARD</STRONG> corresponds to the VT100 symbol for newline
+
+       <STRONG>o</STRONG>   <STRONG>ACS_LANTERN</STRONG> corresponds to the VT100 symbol for vertical tabulation
+
+       AT&amp;T defined <STRONG>ACS_</STRONG> names for the most useful graphic symbols, as well as
+       for its own.  Its header file commented:
+
+       /*
+        * Standard alternate character set.  The current ACS world is evolving,
+        * so we support only a widely available subset: the line drawing characters
+        * from the VT100, plus a few from the Teletype 5410v1.  Eventually there
+        * may be support of more sophisticated ACS line drawing, such as that
+        * in the Teletype 5410, the HP line drawing set, and the like.  There may
+        * be support for some non line oriented characters as well.
+        *
+        * Line drawing ACS names are of the form ACS_trbl, where t is the top, r
+        * is the right, b is the bottom, and l is the left.  t, r, b, and l might
+        * be B (blank), S (single), D (double), or T (thick).  The subset defined
+        * here only uses B and S.
+        */
+
+       Although these less-useful graphic symbols were not given  names,  they
+       were  used  in  <EM>terminfo</EM> entries.  The <EM>ncurses</EM> developers invented ACS-
+       prefixed names for them.

+and a second-hand list of their character descriptions has come to light,
+which identifies them as VT100 special characters.
+.PP
+The DEC Special Character and Line Drawing Set (VT100) is indexed by
+an ASCII character in the range 96 (`) to 126 (~).
+That index character is part of the definition for the curses
+.B \%ACS_
+symbols.
+The VT100 special characters can be categorized in three groups:
+.bP
+useful graphic symbols with a standard
+.B \%ACS_
+symbol,
+(e.g., the line-drawing symbols),
+.bP
+possibly useful characters (these non-standard symbols),
+.bP
+representations of control characters (e.g., newline and vertical tabulation).
+.PP
+A few
+.B \%ACS_
+symbols do not fit into DEC's VT100 scheme.
+The AT&T Teletype 5410v1 arrow symbols and
+.B \%ACS_BLOCK
+use indices outside the range 96 to 126.
+Two of the Teletype symbols use indices in that range,
+with different meaning versus the VT100:
+.bP
+.B \%ACS_BOARD
+corresponds to the VT100 symbol for newline
+.bP
+.B \%ACS_LANTERN
+corresponds to the VT100 symbol for vertical tabulation
+.PP
+AT&T defined
+.B \%ACS_
+names for the most useful graphic symbols,
+as well as for its own.
+Its header file commented:
+.sp
+.EX
+/*
+ * Standard alternate character set.  The current ACS world is evolving,
+ * so we support only a widely available subset: the line drawing characters
+ * from the VT100, plus a few from the Teletype 5410v1.  Eventually there
+ * may be support of more sophisticated ACS line drawing, such as that
+ * in the Teletype 5410, the HP line drawing set, and the like.  There may
+ * be support for some non line oriented characters as well.
+ *
+ * Line drawing ACS names are of the form ACS_trbl, where t is the top, r
+ * is the right, b is the bottom, and l is the left.  t, r, b, and l might
+ * be B (blank), S (single), D (double), or T (thick).  The subset defined
+ * here only uses B and S.
+ */
+.EE
+.PP
+Although these less-useful graphic symbols were not given names,
+they were used in
+.I \%terminfo
+entries.
 The
 .I \%ncurses
 developers invented ACS-prefixed names for them.
