<p>
Asio includes classes for creating and manipulating serial ports in a portable
manner. For example, a serial port may be opened using:
</p>
<pre class="programlisting"><span class="identifier">serial_port</span> <span class="identifier">port</span><span class="special">(</span><span class="identifier">my_io_service</span><span class="special">,</span> <span class="identifier">name</span><span class="special">);</span>
</pre>
<p>
where name is something like <code class="computeroutput"><span class="string">"COM1"</span></code>
on Windows, and <code class="computeroutput"><span class="string">"/dev/ttyS0"</span></code>
on POSIX platforms.
</p>
<p>
Once opened, the serial port may be used as a <a class="link" href="core/streams.html" title="Streams, Short Reads and Short Writes">stream</a>.
This means the objects can be used with any of the <a class="link" href="../reference/read.html" title="read">read()</a>,
<a class="link" href="../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../reference/write.html" title="write">write()</a>,
<a class="link" href="../reference/async_write.html" title="async_write">async_write()</a>, <a class="link" href="../reference/read_until.html" title="read_until">read_until()</a>
or <a class="link" href="../reference/async_read_until.html" title="async_read_until">async_read_until()</a>
free functions.
</p>
<p>
The serial port implementation also includes option classes for configuring
the port's baud rate, flow control type, parity, stop bits and character
size.

<p>
Serial ports are available on all POSIX platforms. For Windows, serial ports
are only available at compile time when the I/O completion port backend is
used (which is the default). A program may test for the macro <code class="computeroutput"><span class="identifier">ASIO_HAS_SERIAL_PORTS</span></code> to determine whether
they are supported.
