I'm not confusing anything.  Although VT100 and IBM are implementations,
they're standards in their own right due to widespread use.

What I'm refering to is that fact that these two emulations are based on a
video display system that uses a fixed format of 80*25 and is non-standard
with respect to NTSC and PAL.

Taking it a bit further, the CUP and HVP ANSI sequences for cursor position
denote 25 lines when talking about a VT100 and an IBM screen.  A PAL Amiga
allows for more than 25 lines, so this sequence is effectively broke in this
situation.

Now, my question is what sort of work around is there for the case where the
system you connect with can't deal with a VT100 or and IBm that has more than
25 lines?

Is there a _right_ way to handle this sort of situation?
