I think that you are correct.  pyserial-2.7 is supposed to be compatible 
with python3.

On further investigation, it turns out that I installed pyserial from my 
distro's package manager.  The default python is 3, with python2 being 
the alternative.  Now, to go with this, I'd installed python-pyserial, 
not python2-pyserial:

==================================================
[root at automate ~]# pacman -Ss pyserial
community/python-pyserial 2.7-4 [installed]
     Multiplatform Serial Port Module for Python
community/python2-pyserial 2.7-4
     Multiplatform Serial Port Module for Python
==================================================

So, yes, my understanding is that the pyserial-2.7 which I have 
installed should be compatible with Python3.

Now I have to work out how to make the report to Chris Liechti - I'll 
try his gmx.net email address.

Thanks for all your advice - I'm enjoying my project, and loving Python!

Regards,
Peter.
