I'm happy to announce a release candidate of pySerial: 2.5-rc2

Whats new since rc1:
- Several small bugfixes.
- updated RFC2217 implementation, client support.
- changed Posix read implementation (error handling for disconnected
- See CHANGES.txt in the distribution for full list.

Source archive and Windows installers can be downloaded from here:

The Windows installer for Python 3.x has py3k in its name, the other one
is for Python 2.x. The source archive's should automatically
convert using 2to3 when run with Python 3.x.


What is pySerial? Quoting from the home page:

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