Serial communication, because of its complexity, can be very difficult to
.
work with at times. Please follow these guidelines (and those in the
"SERIN Troubleshooting" section of the SERIN command description)
when developing a project using the SERIN and SEROUT commands:
1. Always build your project in steps.
a. Start with small, manageable pieces of code, that deals with
serial communication) and test them, one at a time.
b. Add more and more small pieces, testing them each time, as
you go.
c. Never write a large portion of code that works with serial
communication without testing its smallest workable pieces
first.
