Specifies the line protocol for data link protocol operation.  The
 possible protocols are:

         DDCMP CONTROL   Specifies a DDCMP multipoint
                         control station.

         DDCMP POINT     Specifies a DDCMP point-to-point
                         line.

         DDCMP TRIBUTARY Specifies a DDCMP multipoint
                         tributary.

         DDCMP DMC       Specifies a DDCMP point-to-point
                         line in DMC compatibility mode.

         ETHERNET        Specifies that the line uses the
                         Ethernet/IEEE 802.3 protocol.

         FDDI            Specifies that the line uses the
                         FDDI protocol.

         LAPB            Specifies that the line  uses
                         the  X25  level  2  protocol.

         LAPBE           Specifies that the line  uses
                         the  X25  level  2  protocol with
                         extended sequencing.
