[Tutor] conversion confusion

[Lloyd Kvam]

 >>> ord('m')
109
 >>> int('6d',16)
109

So int(value2add,16) should give you the right number.

I assume this relates to the serial processing that you've written about in
the past.  Did you create value2add by using a hex funtion on a character?
Would it be feasible to simply use ord on the original character?
