Heh, not quite, as you usually want the _second_ serial interface to sync off of, the first one is not useful at all (well, some tools use it, but 99% of the users never will care about it.) And then there's the fun problem of some Sony devices creating two serial "devices" where the second one is just a "fake" one, and you really need to connect to the first.
