When I messed with using vt100 on an ansi ibm bbs, the only problem I
came accross is the save/restore cursor codes are different.  And the
bbs I'm thinking of, used them often, probibly because of the way it
stored its graphic images.

>>If you run AGATE, and call a IBM board, any color code will screw up

After reading the first message of this thread, I downloaded agate to
see what it was like.  It uses double hi-res, black and white mode for
its display.  It took me awhile to find apple-4 sets 2400 bps.  I never
did find keys to set parity.  So if you call somewhere that uses parity,
better not count on a readable display.  A local bbs has a multi-color
graphic and agate handled it without any problems, except for not seeing
color.  It did filter out the color commands for me.  As far as speed
goes, it does keep up with 2400 nicely.

If you have a list of the ANSI escape codes, I'd like to get them.  I have
a communication program I wrote that I would like to add the extra codes
in.  I hope to convert this program to a cda sometime this summer before
I let it loose on everyone.  Currently it's a prodos 8 application.

How has it changed?  Certain graphic characters change slightly or change
a lot?  What do I need to watch out for?
