<p class="Pp">The <code class="Nm">umcs</code> driver provides support for
various multiport serial adapters based on the MosCom MCS7820 and MCS7840
chips. They are 2- or 4-port adapters with full-featured 16550-compatible
UARTs and very flexible baud generators. Also, these chips support
RS422/RS485 and IrDA operations.</p>
<p class="Pp">The device is accessed through the <a class="Xr">ucom(4)</a>
driver which makes it behave like a <a class="Xr">tty(4)</a>.</p>
<p class="Pp">Different ports on device are presented as sub-units, like
<span class="Pa">/dev/ttyU0.1</span> and
<span class="Pa">/dev/ttyU0.2</span>.</p>
