tty: i386: rs232 fix

. ignore interrupt (stop interrupt check loop) if
  interrupt bit not set; limit loop too
. mask off other bits when testing bits in the status register
. this fixes rs232 output that would otherwise never get re-triggered
  as too many bits were set in the status byte to match the
  possibilities.
