Why not read the data from within your program?

Take a look at these search results in codeproject. If you want some high quality solution you will need to understand and work withOverlapped I/O. Believe me now or you will after some weeks. ;-)

As Jochen already suggested suggested, usually you use the same program to read from and write to the serial port. Since your application already writes to then it is the best candidate for reading from. You might for instance just log the received data to a file or display it on the console window.
