<p class="Pp">The <code class="Nm">scc</code> device driver provides support for
    various classes of SCCs. It is an umbrella driver that delegates control of
    each independent communication channel to subordinate drivers. These
    subordinate drivers, like <a class="Xr">uart(4)</a>, take care of the
    details of the communication itself.</p>
