Overview
========

This module encapsulates the access for the serial port. It provides backends
for Python_ running on Windows, OSX, Linux, BSD (possibly any POSIX compliant
system) and IronPython. The module named "serial" automatically selects the
appropriate backend.

It is released under a free software license, see LICENSE_ for more
details.

Features
========
- Same class based interface on all supported platforms.
- Access to the port settings through Python properties.
- Support for different byte sizes, stop bits, parity and flow control with
  RTS/CTS and/or Xon/Xoff.
- Working with or without receive timeout.
- File like API with "read" and "write" ("readline" etc. also supported).
- The files in this package are 100% pure Python.
- The port is set up for binary transmission. No NULL byte stripping, CR-LF
  translation etc. (which are many times enabled for POSIX.) This makes this
  module universally useful.
- Compatible with :mod:`io` library
- RFC 2217 client (experimental), server provided in the examples.
