    Change serial "open" functions to throw exception

    remote.c assumes that a failure to open the serial connection will set
    errno.  This is somewhat true, because the Windows code tries to set
    errno appropriately -- but only somewhat, because it isn't clear that
    the "pex" code sets it, and the tcp code seems to do the wrong thing.
    It seems better to simply have the serial open functions throw on
    error.
