communication with i/o port

Hi,
Please inform me, how i can communicate to i/o port using functions provided by window's.

Thanks

You can get a handle to an I/O port with the CreateFile() API routine. Look it up in the help or at MSDN, particulaly the section dealing with "Communication Resources".

Once you have a handle, you can use the handle based I/O routines, (ReadFile(), WriteFile() etc.).

Here is a link to one solution from MSDN.
