I/O via serial (COM) ports

Anybody know how you can change the standard I/O so that you can I/O via COM
ports??

Also in C++ if thats possible?? (maybe easier)

TIA

Not possible in standard C++ either.

The filename passed to fopen() is interpreted in an
implementation-defined way - some implementations will interpret certain
strings as a request to open a COM port. To find out whether your
implementation can do this, and if so, which strings to use, ask in a
newsgroup dedicated to your platform.

As others have said, you must use platform-specific functions. A
Google search for "serial" on comp.os.ms-windows.programmer.win32
should find several posts answering this FAQ; some of them by me.
