Driver was crashing. Change nulls and emptys to 0s to allow typecasti… #35

Driver was crashing on a real PTU. This happened because the very first request made to the PTU after powering on (not initialize sequence) was returning a null/empty character.

To prevent this crashing and to make sure the user doesn't have to launch twice, this will turn any emptys/nulls to "0" so that typecasting works.
