I've use Chris Liechti's pySerial very successfully several times on 
Python 2.7 and earlier and just a test with 3.6. Easy enough to access 
it from Python threads. I'm stuck with Windoze so have used COMx: port 
access to both PC native serial port (I have old kit) and USB virtual 
serial ports. No idea about xNix.
