| |
| |
| 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 |
| --------------------------- |

| Suggested by Bernhard Bender |

| (COM10 is internally translated to \\.\COM10 etc.) |

| - add port_publisher example |
| - experimental RFC-2217 server support (examples/rfc2217_server.py) |
| - add ``getSettingsDict`` and ``applySettingsDict`` serial object methods |

| 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. |
| |
| Bugfixes: |
| |
| - [Bug 2925854] test.py produces exception with python 3.1 |
| - [Bug 3029812] 2.5rc2 readline(s) doesn't work |
| |
| Bugfixes (posix): |
| |
| - [BUG 3006606] Nonblocking error - Unix platform |
| |
| Bugfixes (win32): |
| |
| - [Bug 2998169] Memory corruption at faster transmission speeds. |
| (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 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 |
