I didn't understand the rest but to loop 20 times a second
 - provided your machine is fast enough! - do this:

while 1:
   sleep(0.05)  # 1/20s delay
   # do something here
   if someCondition: break

Are you sending or polling(reading)?
Or both? Do you send to get a result back? 

I don't understand sorry.
