[comp.sys.apple2] SnowTerm 2.06

    Does this version of SnowTerm display ANSI graphics?  I tried logging on
to some IBM BBS's with ANSI screens, but I got the usual low-ASCII
representation of the graphics.  However, I was viewing a VT-100 animated text
file (less'ed a file from UNIX), and I saw ANSI characters!  There was a
single-line border around some text, and it wasn't created with the vertical
bar or underscore characters.  If I interrupt the text at the right place
(when the 'ANSI' is still turned on), whatever I type in comes out in
high-ASCII instead!  I try to capture the escape sequence needed to turn this
feature on.

SnowTerm is a VT100 emulator.  Version 2.06 and every previous version has the
capability of displaying the VT100 special graphics character set.  This is
different than the IBM PC so called ANSI character set which is activated by
the MSB of the character.  The VT100 special character set is an alternate
font that is mapped in place of the lower case alpha characters.  The MSB
of the ASCII character has no affect at all.

To turn on the special graphics character set, one must first specify
which font is desired.  This is done with the sequence ESC ) 0.  After that
a control-N character will select the special graphics character set and
a control-O will select the normal character set.  Again, the special grahpics
character set only replaces the lower case alpha characters.
