I am just messing around trying to get pyserial to work with 3.0.
I am stuck on this line:
if type(port) in [type(''), type(u'')]
how can I convert this to 3.0? I tried changing the u to a d that did
not do anything.
Thanks

But, I have been able to fix the problem (hope it helps somebody):

The opposite argument is that it may be better left up to the application that
