[section:serial_ports Serial Ports]

Boost.Asio includes classes for creating and manipulating serial ports in a portable
manner. For example, a serial port may be opened using:

  serial_port port(my_io_service, name);

where name is something like `"COM1"` on Windows, and `"/dev/ttyS0"` on POSIX
platforms.

Once opened the serial port may be used as a stream. This means the objects can
be used with any of the [link boost_asio.reference.read read()], [link
boost_asio.reference.async_read async_read()], [link boost_asio.reference.write write()],
[link boost_asio.reference.async_write async_write()], [link
boost_asio.reference.read_until read_until()] or [link
boost_asio.reference.async_read_until async_read_until()] free functions.

The serial port implementation also includes option classes for configuring the
port's baud rate, flow control type, parity, stop bits and character size.

[heading Notes]

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
`BOOST_ASIO_HAS_SERIAL_PORTS` to determine whether they are supported.
