SubjectRe: TTY speedup patch/Menuconfig speed??
Thanks for your helpful tidbit.  I haven't had rmcup in my linux terminfo
definition for a very long time. In fact, I rewrote my linux definition
from scratch quite some time back. I did, however, remove "rmcup" from my
xterm definitions and that does improve Menuconfig's "cosmetics" while
running.

So, for all you Menuconfig users out there frustrated with the screen
redraws, especially under an xterm, follow Johns suggestion and remove the
rmcup= entry from your terminfo definitions and recompile (tic). If you
have an adverse effect, (I think you won't), then put it back.

Thanks again John!
