    November 02, 2011

    • 🚚 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

    • 🆕 new URL type: hwgrep:// uses list_ports module to search for ports by their description
    • several 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

  • v2.5 Changes

    July 22, 2010

    🆕 New Features:

    • 0️⃣ [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 and 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

    • [Bug 2886763] hComPort doesn't get initialized for Serial(port=None)
