<p class="Pp">The <code class="Nm">ucom</code> driver attaches to USB modems,
serial ports, and other devices that need to look like a tty. The
<code class="Nm">ucom</code> driver shows a behaviour like a
<a class="Xr">tty(4)</a>. This means that normal programs such as
<a class="Xr">tip(1)</a> or <a class="Xr">pppd(8)</a> can be used to access
the device.</p>
<p class="Pp">The <var class="Va">portno</var> locator can be used to decide
which port to use for device that have multiple external ports.</p>
<p class="Pp">Note that while <code class="Nm">ucom</code> supports the
(undocumented) pulse-per-second API normally used on conventional serial
ports, USB serial devices typically have a varying latency around 1 ms due
to the USB frame structure.</p>
<p class="Pp">The ttyXX devices are traditional dial-in devices; the dtyXX
devices are used for dial-out. (See <a class="Xr">tty(4)</a>.)</p>
