  Modified files:
    sys/i386/isa         sio.c 
  Log:
  Always call ttwwakeup() before returning from comstart().  It isn't
  necessary to call it when the tty layer's output state has not been
  changed, but siostop() sometimes changes the TS_BUSY state and then
  calls comstart() mainly for its side effect of calling ttwwakeup().
