   Line            local entity    Specifies the Modem Connect Line on
                   name            which the SDLC protocol operates.
                                   For more information about Modem

   Capability      primary |       Specifies the capability of the
                   secondary |     Station subentities of this Link
                   negotiable      entity.  Negotiable stations can
                                   become either primary or secondary.
                                   The default is negotiable.

   Configuration   pointtopoint |  Specifies whether the Link supports
                   multipoint      only a point-to-point connection or

                                   connection.  Multipoint supports one
                                   or more than one connection.  The
                                   default is pointtopoint.  The Peer
                                   Server does not support multipoint
                                   primary connections.

   Connection      nonswitched |   Specifies whether the Link supports
   Type            switched        switched or nonswitched connections.

   Receive         (1-32764)       Specifies the maximum frame size
   Frame Size                      (excluding the header) that can be

                                   this Link. The default is 1000.

   Reply Timer     (100-60000)     Specifies the time (in milliseconds)
                                   to wait for an acknowledgment before
                                   starting the recovery procedure. The
                                   default is 3000.

   Retry           (0-128)         Specifies that, when the Link is
   Maximum                         secondary, this is the maximum
                                   number of times a frame is
                                   retransmitted before assuming a
                                   fatal error.  When the Link is

                                   multipoint primary. The default is

                                   multipoint primary mode. Yes
                                   means that PIUs that arrive for

                                   by the position of station service
                                   order entries in the Service Order
