We do not have any specific guides or example code to recommend to help you with serial communication, but you might be able to find something by doing an online search for “c serial example” or something similar. This thread has an example that shows how to use a serial port in C in Windows (it is for a Maestro servo controller, but you should be able to modify it to work). Alternatively, if you can use .NET (C++, C#, or VB) instead of C, Microsoft provides a SerialPort class that should help you.
