<p class="Pp">The <code class="Nm">tcom</code> driver provides support for the
    Byte Runner Technologies TC-400 and TC-800 series boards that multiplex
    together up to four or eight EIA RS-232C (CCITT V.28) communications
    interfaces.</p>
<p class="Pp">Each <code class="Nm">tcom</code> device is the master device for
    up to eight <code class="Nm">com</code> devices. The kernel configuration
    specifies these <code class="Nm">com</code> devices as slave devices of the
    <code class="Nm">tcom</code> device, as shown in the synopsis. The slave ID
    given for each <code class="Nm">com</code> device determines which bit in
    the interrupt multiplexing register is tested to find interrupts for that
    device. The port specification for the <code class="Nm">tcom</code> device
    is used to compute the base addresses for the <code class="Nm">com</code>
    subdevices and the port for the interrupt multiplexing register.</p>
<p class="Pp">Not all possible configuration options are currently supported
    (for example, speeds beyond 115200 baud are not currently supported).</p>
