Maybe I'm missing something, but I fail to see why integers or character arrays would by any more implicitly IN than other types?... Perhaps IN is simply the default in general, and it's only explicitly specified in most interfaces for clearity? But that's pure speculation of course :-) (BTW, the same "mode" parameter is actually explicitly marked as IN in the other device_ RPCs -- so I guess it's just some hiccup that it's missing in device_open()...) -antrik-
