ANSI graphics could be one of two things.  First would be the IBM extended
character set, ie, decimal 128 through decimal 255.  These characters allow
the user to draw boxes and the like on the screen.  The shapes of these
characters, and the value to create it is found in many sources.  The BASIC
programming manuals list them, ie, Microsoft QuickBasic and others.

The use of the IBM Extended character set requires that you receive your text
into the terminal with 8 bit, no parity set.  You must not strip off the 8th
bit of the character.

The other ANSI graphics could mean the characters that are built into the
DEC VT-nnn terminals.  These characters are listed in the various DEC VT-nnn
manuals.  Again, you must not strip off the 8th bit.  I don't remember for
sure, but these characters may also be set by using ESC sequences.  I don't
know for sure, since I don't have one of these terminals around.  I only
really know about the IBM Extended character set, mention previously.
