redirecting /dev/ttyS0 -> stdin

Hi all,
i've got a little problem with a barcode scanner.
the barcode scanner is connected to /dev/ttyS0 and if i say:
cat /dev/ttyS0
i see a good output of a barcode.

now my question is, how do i redirect it to the stdin in that way, that it will be handled the exactly same way as a keyboard (yes, even in X)

maybe it is possible only in X if i could manage to create an InputDevice for it? (i don't need to work with it in the shell)

i hope you can help.

Hmmm... not clear what you are trying to do here - cat will send the input to stdout (terminal screen) and this is what happens to anything from stdin too. Anywhere stdin can co, cat can send it... so what was the question?

(I suspect you are trying to do something that has a more common approach to it.)

I think that goestin want to redirect all input that come from /dev/ttyS0 to the STDIN as the input of the keyboard, so he want to have something as keyboard emulator...
