  There is a bug in A/UX (Even in 1.1 Betas it seems) where every now
and then a things get confused and SIGIO is turned on for that tty no
matter what you do.
  I fixed some bugs in the A/UX port of GnuEmacs along with adding a
null interupt function to catch the SIGIO.  Affixed is my diff from
GnuEmacs version 18.52.
