I've done a class that communicates with the serial port. The problem is that for some reason after booting the machine and starting my program, I cannot receive anything, but I can send bytes to the port. So for it to work, I open up a HyperTerminal on the com port and write in it. After that I start receiving information from the port.

Info on the program:

I open the com port with an overlapped structure to have asynchronous reading and writing. I use ReadFile and WriteFile with an Overlapped structure.

Thanks in advance.
