  Modified:    sys/i386/isa  si.c
  Log:
  Apply a bandaid to a problem elsewhere in the driver, when the process is
  blocked in a write() while waiting for the output to drain, sleep only
  for tp->t_timeout, not forever.  This only seems to happen when there is
  either a modem lockup holding the hardware flow control down, or due to
  some problem in the driver with processes attempting to write after the
  modem has hung up (eg: elm, tf).
