Using the serial port is a bit interesting, but not terribly difficult once you understand how it works. If you just want a drop in solution, there are C++ classes for the serial port that are freely available on the web. As to the details...you create a file using CreateFile, use the file handle returned to set up the details of communication (baud rate, handshaking, etc.) with SetCommState (and SetCommTimeouts) then use WriteFile and ReadFile to retrieve the data from the port.

Please direct us to the C++ classes available on the internet.

Thanks
