The setXON() Method for Posix-Systems is wrong impelemented.
Two variables are wrong.

Error Message:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.4/site-packages/serial/serialposix.py", line 622, in setXON
if not self.hComPort: raise portNotOpenError
AttributeError: 'Serial' object has no attribute 'hComPort'


Steps to reproduce:
Use the setXON() Method.

Solution:

Change the variables in
/usr/lib/python3.4/site-packages/serial/serialposix.py

to the correct ones.
hComPort -> _isOpen
enable -> level
