Hi, All:
I need to use RS232 port on the PC to read to my window application and
write out via the same port using separate the thread than my main
thread.  I plan to use .NET C++ MFC Application.

I have been reading all the useful information on the web.  I found
Ramon deKlein 's "Serial library for C++" is most closed article I can
use.

Has someone used his library on .NET C++ environment?  Which class
(CSerial or CSerialEx) I should use?  I would like to use overlapped
mode to give user better response.

Or other suggestion?

Thank you
