I have tried using maxchar values of up to 100 and I still get a
segmentation fault......
If it's any help here is what the data (the board_id) is:
As viewed in a file in Hex: 0100F120
As displayed on the screen after being read from the file: 552665089 (this
is the result of doing a cout of the data)....
