<p class="Pp">The <code class="Nm">ppp</code> interface allows serial lines to
    be used as network interfaces using the
    <a class="permalink" href="#Point-to-Point"><i class="Em" id="Point-to-Point">Point-to-Point
    Protocol</i></a> (PPP). The <code class="Nm">ppp</code> interface can use
    various types of compression and has many features over the SLIP protocol
    used by the <a class="Xr">sl(4)</a> interface.</p>
<p class="Pp">Supported options are:</p>
<dl class="Bl-tag Bl-compact">
