<p class="Pp">The <code class="Nm">spif</code> driver provides support for the
    Sun Serial/Parallel Interface card (Sun part number 501-1931), which is
    based on the Cirrus Logic CD180 octal serial controller and the Cirrus Logic
    PPC2 parallel port controller.</p>
<p class="Pp">The device minor numbers for this driver are encoded as
  follows:</p>
