        !            28: .I ddn
        !            29: device provides a DDN Standard Mode X.25 interface to an IMP using
        !            30: the ACC ACP625 X.25 board.  It is normally used for connecting to
        !            31: the Defense Data Network (DDN).  The controller itself is not accessible
        !            32: to users, but instead provides a network interface for the
        !            33: Internet Protocol described in
