ieee488, I am interested to understand your comment. I have turned to Arduino Create because I continually have problems trying to allocate a comport. I use a mac and it seems almost random if a comport is allocated, further I even went to the expense of buying a (cheap but good) windows laptop with no other applications loaded only to find that it still seemed random as to which comport is allocated. I'm sure with your handle you should be able to tell me why. Arduino Create on the other hand worked first time and is totally consistent.
Cheers
Chris
