         Then that's like pine and pico on unix.

         But will they change the remote workstation

        ANSI doesn't necessarily have 'high bits" set,
it uses VT100 format with charact decimal 27 being the
"ESCAPE" or beginning character in an "ESCAPE sequence",
that looks like ]]35m to change foreground color, ]]45m
to change background color, ]]32;45m to change both,
and ]]20;10H to position the cursor if needed.
        Clear Entire Screen is ]]2J.

        So that part would have been easy to implement
in HTML, except the characters would have to be all the
same size and fixed width.

        The IBM high characters are simply characters
128 through 255 (255 being blank).    Usenet is 8 bits
capable now, so no bits have to be set, the character
decimal 32 through 255 is simply sent as a single byte.
        It would be easy to create a fixed size and
width  ANSI character set for windows, identical to the
IBM character set.
        And I don't think translating the color info
from ]]34;45m to "foreground color=<AABBCC>" background
color=<DDEEFF>". just a little less code to transmit,
but with less color combinations. 

        There is a newsgroup that sends ANSI, it is 
a tw group with "literal" in the newsgroup name.
