        !            11: .I ddn
        !            12: device provides a DDN Standard Mode X.25 interface to an IMP using
        !            13: the ACC ACP625 X.25 board.  It is normally used for connecting to
        !            14: the Defense Data Network (DDN).  The controller itself is not accessible
        !            15: to users, but instead provides a network interface for the
