Problem with python-serial 2.6-1.1

I'm running Debian Wheezy Jessie, and I had pretty big problem with the new(ish) version of python-serial. On 2.6-1.1, elm.py would change the stty settings after the first run. That is, the program ran once but hung on the second try.

After downgrading to python-serial 2.5-2.1, everything worked again.

I'm not 100% on the steps to reproduce faithfully on another computer, it's just a problem I had on mine.

Need to handle no response condition

PID may return NO DATA even when the car is running. Need to handle this condition
