======================== pySerial Release Notes ======================== Version 1.0 13 Feb 2002 --------------------------- - First public release. - Split from the pybsl application (see http://mspgcc.sourceforge.net) New Features: - Added Jython support Version 1.1 14 Feb 2002 --------------------------- Bugfixes: - Win32, when not specifying a timeout - Typos in the Docs New Features: - added ``serialutil`` which provides a base class for the ``Serial`` objects. - ``readline``, ``readlines``, ``writelines`` and ``flush`` are now supported see README.txt for deatils. Version 1.11 14 Feb 2002 --------------------------- Same as 1.1 but added missing files. Version 1.12 18 Feb 2002 --------------------------- Removed unneded constants to fix RH7.x problems. Version 1.13 09 Apr 2002 --------------------------- Added alternate way for enabling rtscts (CNEW_RTSCTS is tried too) If port opening fails, a ``SerialException`` is raised on all platforms Version 1.14 29 May 2002 --------------------------- Added examples to archive Added non-blocking mode for ``timeout=0`` (tnx Mat Martineau) Bugfixes: - win32 does now return the remaining characters on timeout Version 1.15 04 Jun 2002 --------------------------- Bugfixes (win32): - removed debug messages - compatibility to win9x improved Version 1.16 02 Jul 2002 --------------------------- Added implementation of RI and corrected RTS/CTS on Win32 Version 1.17 03 Jul 2002 --------------------------- Silly mix of two versions in win32 code corrected Version 1.18 06 Dec 2002 --------------------------- Bugfixes (general): - remove the mapping of flush to the destructive flushOutput as this is not the expected behaviour. - readline: EOL character for lines can be chosen idea by John Florian. Bugfixes (posix): - cygwin port numbering fixed - test each and every constant for it's existence in termios module, use default if not existent (fix for Bug item #640214) - wrong exception on nonexistent ports with /dev file. bug report by Louis Cordier Bugfixes (win32): - RTS/CTS handling as suggested in Bug #635072 - bugfix of timeouts brought up by Markus Hoffrogge Version 1.19 19 Mar 2003 --------------------------- Bugfixes (posix): - removed ``dgux`` entry which actually had a wrong comment and is probably not in use anywhere. Bugfixes (win32): - added ``int()`` conversion, [Bug 702120] - remove code to set control lines in close method of win32 version. [Bug 669625] Version 1.20 28 Aug 2003 --------------------------- - Added ``serial.device()`` for all platforms Bugfixes (win32): - don't recreate overlapped structures and events on each read/write. - don't set unneeded event masks. - dont use DOS device names for ports > 9. - remove send timeout (its not used in the linux impl. anyway). Version 1.21 30 Sep 2003 --------------------------- Bugfixes (win32): - name for COM10 was not built correctly, found by Norm Davis. Bugfixes (examples): - small change in ``miniterm.py`` that should mage it run on cygwin, [Bug 809904] submitted by Rolf Campbell. Version 2.0b1 1 Oct 2003 --------------------------- Transition to the Python 2.0 series: - New implementation only supports Python 2.2+, backwards compatibility should be maintained almost everywhere. The OS handles (like the ``hComPort`` or ``fd`` attribute) were prefixed with an underscore. The different names stay, as anyone that uses one of these has to write platform specific code anyway. - Common base class ``serialutil.SerialBase`` for all implementations. - ``PARITY_NONE``, ``PARITY_EVEN``, ``PARITY_ODD`` constants changed and all these constants moved to ``serialutil.py`` (still available as ``serial.PARITY_NONE`` etc. and they should be used that way) - Added ``serial.PARITY_NAMES`` (implemented in ``serialutil.PARITY_NAMES``). This dictionary can be used to convert parity constants to meaningful strings. - Each Serial class and instance has a list of supported values: ``BAUDRATES``, ``BYTESIZES``, ``PARITIES``, ``STOPBITS``Ggg (i.e. ``serial.Serial.BAUDRATES or s = serial.Serial; s.BAUDRATES``) these values can be used to fill in value sin GUI dialogs etc. - Creating a ``Serial()`` object without port spec returns an unconfigured, closed port. Useful if a GUI dialog should take a port and configure it. - New methods for ``serial.Serial`` instances: ``open()``, ``isOpen()`` - A port can be opened and closed as many times as desired. - Instances of ``serial.Serial`` have ``baudrate``, ``bytesize``, ``timeout`` etc. attributes implemented as properties, all can be set while the port is opened. It will then be reconfigured. - Improved ``__doc__``'s. - New ``test_advanced.py`` for the property setting/getting testing. - Small bugfix on posix with get* methods (return value should be true a boolean). - added a ``__repr__`` that returns a meaningful string will all the serial setting, easy for debugging. - The serialposix module does not throw an exception on unsupported platforms, the message is still printed. The idea that it may still work even if the platform itself s not known, it simply tries to do the posix stuff anyway (It's likely that opening ports by number fails, but by name it should work). Version 2.0b2 4 Oct 2003 --------------------------- - Added serial port configuration dialog for wxPython to the examples. - Added terminal application for wxPython with wxGlade design file to the examples. - Jython support is currently broken as Jython does not have a Python 2.2 compatible release out yet Version 2.0 6 Nov 2003 --------------------------- - Fixes ``setup.py`` for older distutils Version 2.1 28 Jul 2004 --------------------------- Bugfixes: - Fix XON/XOFF values [Bug 975250] Bugfixes (posix): - ``fd == 0`` fix from Vsevolod Lobko - netbsd fixes from Erik Lindgren - Dynamicaly lookup baudrates and some cleanups Bugfixes (examples): - CRLF handling of ``miniterm.py`` should be more consistent on Win32 and others. Added LF only command line option - Multithreading fixes to ``wxTerminal.py`` (helps with wxGTK) - Small change for wxPython 2.5 in ``wxSerialConfigDialog.py`` [Bug 994856] New Features: - Implement write timeouts (``writeTimeout`` parameter) Version 2.2 31 Jul 2005 --------------------------- Bugfixes: - [Bug 1014227]: property <del> broken - [Bug 1105687]: ``serial_tcp_example.py``: ``--localport`` option - [Bug 1106313]: device (port) strings cannot be unicode Bugfixes (posix): - [Patch 1043436] Fix for [Bug 1043420] (OSError: EAGAIN) - [Patch 1102700] ``fileno()`` added - ensure disabled PARMRK Bugfixes (win32): - [Patch 983106]: keep RTS/CTS state on port setting changes New Features: - ``dsrdtr`` setting to enable/disable DSR/DTR flow control independently from the ``rtscts`` setting. (Currenly Win32 only, ignored on other platforms) Version 2.3 19 Jun 2008 --------------------------- New Features: - iterator interface. ``for line in Serial(...): ...`` is now possible Suggested by Bernhard Bender - ``sendBreak()`` accepts a ``duration`` argument. Default duration increased. - win32 handles \\.\COMx format automatically for com ports of higher number (COM10 is internally translated to \\.\COM10 etc.) - miniterm.py has a new feature to send a file (upload) and configurable special characters for exit and upload. Refactored internals to class based structure (upload and class refactoring by Colin D Bennett) Bugfixes: - [Bug 1451535] TCP/serial redirect example "--help" - update VERSION variable - update wxSerialConfigDialog.py and wxTerminal.py compatibility with wxPython 2.8 (Peleg) - Check for string in write function. Using unicode causes errors, this helps catching errors early (Tom Lynn) Bugfixes (posix): - [Bug 1554183] setRTS/setDTR reference to non existing local "on" - [Bug 1513653] file descriptor not closed when exception is thrown - FreeBSD now uses cuadX instead of cuaaX (Patrick Phalen) Bugfixes (win32): - [Bug 1520357] Handle leak - [Bug 1679013] Ignore exception raised by SetCommTimeout() in close(). - [Bug 1938118] process hang forever under XP Version 2.4 6 Jul 2008 --------------------------- New Features: - [Patch 1616790] pyserial: Add inter-character timeout feature - [Patch 1924805] add a setBreak function - Add mark/space parity - Add .NET/Mono backend (IronPython) Bugfixes (posix): - [Bug 1783159] Arbitrary baud rates (Linux/Posix) Bugfixes (win32): - [Patch 1561423] Add mark/space parity, Win32 - [Bug 2000771] serial port CANNOT be specified by number on windows - examples/scanwin32.py does no longer return \\.\ names - fix \\.\ handling for some cases Bugfixes (jython): - The Jython backend tries javax.comm and gnu.io (Seo Sanghyeon) Version 2.5-rc1 2009-07-30 --------------------------- New Features: - Python 3.x support (through 2to3) - compatible with Python io library (Python 2.6+) - Support for Win32 is now written on the top of ctypes (bundled with Python 2.5+) instead of pywin32 (patch by Giovanni Bajo). - 1.5 stop bits (STOPBITS_ONE_POINT_FIVE, implemented on all platforms) - miniterm application extended (CTRL+T -> menu) - miniterm.py is now installed as "script" - add scanlinux.py example - add port_publisher example - experimental RFC-2217 server support (examples/rfc2217_server.py) - add ``getSettingsDict`` and ``applySettingsDict`` serial object methods - use a ``poll`` based implementation on Posix, instead of a ``select`` based, provides better error handling [removed again in later releases]. Bugfixes: - Improve and fix tcp_serial_redirector example. - [Bug 2603052] 5-bit mode (needs 1.5 stop bits in some cases) Bugfixes (posix): - [Bug 2810169] Propagate exceptions raised in serialposix _reconfigure - [Bug 2562610] setting non standard baud rates on Darwin (Emmanuel Blot) Bugfixes (win32): - [Bug 2469098] parity PARITY_MARK, PARITY_SPACE isn't supported on win32 - [SF 2446218] outWaiting implemented - [Bug 2392892] scanwin32.py better exception handling - [Bug 2505422] scanwin32.py Vista 64bit compatibility Version 2.5-rc2 2010-01-02 --------------------------- New Features: - Documentation update, now written with Sphinx/ReST - Updated miniterm.py example - experimental RFC-2217 client support (serial.rfc2217.Serial, see docs) - add ``loop://`` device for testing. - add ``serial.serial_for_url`` factory function (support for native ports and ``rfc2217``, ``socket`` and ``loop`` URLs) - add new example: ``rfc2217_server.py`` - tests live in their own directory now (no longer in examples) Bugfixes: - [Bug 2915810] Fix for suboption parsing in rfc2217 - Packaging bug (missed some files) Bugfixes (posix): - improve write timeout behavior - [Bug 2836297] move Linux specific constants to not break other platforms - ``poll`` based implementation for ``read`` is in a separate class ``PosixPollSerial``, as it is not supported well on all platforms (the default ``Serial`` class uses select). - changed error handling in ``read`` so that disconnected devices are detected. Bugfixes (win32): - [Bug 2886763] hComPort doesn't get initialized for Serial(port=None) Version 2.5 2010-07-22 --------------------------- New Features: - [Bug 2976262] dsrdtr should default to False ``dsrdtr`` parameter default value changed from ``None`` (follow ``rtscts`` setting) to ``False``. This means ``rtscts=True`` enables hardware flow control on RTS/CTS but no longer also on DTR/DSR. This change mostly affects Win32 as on other platforms, that setting was ignored anyway. - Improved xreadlines, it is now a generator function that yields lines as they are received (previously it called readlines which would only return all lines read after a read-timeout). However xreadlines is deprecated an not available when the io module is used. Use ``for line in Serial(...):`` instead.

(bug introduced in 2.5-rc1) Version 2.6 2011-11-02 --------------------------- New Features: - Moved some of the examples to serial.tools so that they can be used with ``python -m`` - serial port enumeration now included as ``serial.tools.list_ports`` - URL handers for ``serial_for_url`` are now imported dynamically. This allows to add protocols w/o editing files. The list ``serial.protocol_handler_packages`` can be used to add or remove user packages with protocol handlers (see docs for details). - new URL type: hwgrep://<regexp> uses list_ports module to search for ports by their description - serveral internal changes to improve Python 3.x compatibility (setup.py, use of absolute imports and more) Bugfixes: - [Bug 3093882] calling open() on an already open port now raises an exception - [Bug 3245627] connection-lost let rfc2217 hangs in closed loop - [Patch 3147043] readlines() to support multi-character eol Bugfixes (posix): - [Patch 3316943] Avoid unneeded termios.tcsetattr calls in serialposix.py - [Patch 2912349] Serial Scan as a Module with Mac Support Bugfixes (win32): - [Bug 3057499] writeTimeoutError when write Timeout is 0 - [Bug 3414327] Character out of range in list_ports_windows - [Patch 3036175] Windows 98 Support fix - [Patch 3054352] RTS automatic toggle, for RS485 functionality. - Fix type definitions for 64 bit Windows compatibility
