i recently posted some kernel patches to allow the zs8530 chips to run
at 76800 baud.  here are some more patches that will allow stty, getty,
uucico, and tip to understand what 76800 means.  these patches assume
that you have replaced 4800 baud (which is what i posted, and have
reposted below).  they also assume that you are running 4.1.2.

one thing that these patches to not fix is termcap padding.  if you are
running a terminal at 76800 and it needs padding, all the
curses/termcap programs are going to think you're running at 4800 baud,
and therefore not provide enough padding for 76800.

*** DISCLAIMER ***
i take no responsibility for any side effects these patches may
have.  if you blow up half of north america, it is not my fault.
look over these patches carefully, and make sure you understand
what they are doing.  keep backups copies of the programs you
are modifying.  pay attention to w/W differences.  be careful!
