The ultimate goal is to send simple messages ("GH", "HC", etc.) to a CMUcam2 and to read what messages I get back. I need help in setting up a serial communications port in Windows. I have seen how to open the port on other threads on this website, but I can't figure out how to write to or read from the serial port. Also how can I see what I am reading and writing to the serial port to verify that the information being transmitted is correct, hyperterminal perhaps? Also I am using Dev C++ to do the programming.
