I have recently purchased a DFRobot RS232 shield for a project that i want to build and I have established that my shield is functioning. What I am trying to achieve is reading serial information from a A&D FZ-200i digital scale. From what I can tell, the scale puts out an ASCII data bit and for the life of me I am struggling to work out how to read the data bit. Please help with some examples of how to read an unknown data bit.
