I'm having a problem getting this class to work. I don't get any message or communication out/in on my serial port. I have verified the serial port is working with a serial, terminal application. I've copied the script exactly as it is given, but get nothing when testing, connected to another pc using hyperterm. Ultimately, I too am trying to communicate with a microcontroller, just as a personal fun project. It's starting to not be much fun at this point. Any suggestions?
