Arch Linux

Description:
When receiving invalid characters from serial, miniterm.py(the useful demo tool for python-pyserial) crashes. I think this is because miniterm.py is not meant to run in python3(the default python for arch).

Steps to reproduce:
* Open a serial port
* Receive invalid data(I managed to do it by playing with the RX wire, but i think wrong baud rates will also work)
* UnicodeEncodeError: 'ascii' codec can't encode character '\x97' in position 0: ordinal not in range(128)

The way I go around this is to use miniterm2(which i think is the same thing with the #! line changed), but it's really annoying having different stuff in makefiles for other OSs. What i suggest is to make python-pyserial(the python3 one) not come with a miniterm.py, and just let the python2-pyserial package take care of it(rename miniterm2.py to miniterm.py).
