I run kermit at home with my AT-clone and a 1200 baud modem.

   When I run emacs and have two or more windows open I am seriously
slowed up or down because most of the time scrolling down in a window results
in the redrawing of that whole window, instead of just scrolling that
window using ANSI commands.  I know it can work right because sometimes
it does, and scrolling to a new line in one window just draws the one new
line and goes fast. I have no Idea why it works fine in some cases but not
others.    If I have only one window open it works fine.

I am just using the standerd termcap entry for a vt100 and I have
the NNANSI.SYS device driver loaded (works great, lightning fast)
which is an enhanced ANSI driver that handles 43 and 50 line modes.
  I have a orchid prodesigner and love it, I can run in BIOS supported
text modes like 50x100 using a 8x12 character or virtually any size
from 8x8 to 8x16.
  Of course I just do a 'stty rows 50 cols 100' to keep emacs aware of
my screen size.
