   8 [section:serial_ports Serial Ports]
   9
  10 Boost.Asio includes classes for creating and manipulating serial ports in a portable
  11 manner. For example, a serial port may be opened using:
  12
  13   serial_port port(my_io_service, name);
  14
  15 where name is something like `"COM1"` on Windows, and `"/dev/ttyS0"` on POSIX
  16 platforms.
  17
  18 Once opened, the serial port may be used as a [link boost_asio.overview.core.streams
  19 stream]. This means the objects can be used with any of the [link
  20 boost_asio.reference.read read()], [link boost_asio.reference.async_read async_read()],
  21 [link boost_asio.reference.write write()], [link boost_asio.reference.async_write
  22 async_write()], [link boost_asio.reference.read_until read_until()] or [link
  23 boost_asio.reference.async_read_until async_read_until()] free functions.
  24
  25 The serial port implementation also includes option classes for configuring the
  26 port's baud rate, flow control type, parity, stop bits and character size.

  42 Serial ports are available on all POSIX platforms. For Windows, serial ports
  43 are only available at compile time when the I/O completion port backend is used
  44 (which is the default). A program may test for the macro
  45 `BOOST_ASIO_HAS_SERIAL_PORT` to determine whether they are supported.
