Your code is using the first argument passed on the command line as the name of the file it's trying to open to read the serial port. What are you specifying for the value of that argument?
I figured out this is more of a library so i'll have to create a program that uses this. Not sure if I'm even going to keep it rather than just write a brand new code library with program. Any more help would be amazing though and its only help me learn!
