The HDLC Link Logical Station entity controls the characteristics of an
   HDLC Logical Station. There is one station for each remote termination of
   a line associated with the HDLC link.  The link name is the link entity
   within the HDLC module and the logical station name refers to the logical
   station.

     COMMAND ADDRESS

         Address the local station uses when sending command frames to the
  	remote station.

     MAINTENANCE MODE

         Whether the station is in maintenance mode. When set to true, the
 	station will be used exclusively for maintenance operations. When
         set to false, the station operates in normal fashion.

 	The limit command sets the value of this attribute to true, and
 	the unlimit to false.

     PROTOCOL STATE

         State of the data link protocol.

         ERROR -        A protocol error occurred. For instance, the logical
                        station received an invalid frame.

         HALTED -       The protocol could not start. For example, there is
                        no client.

         INITIALIZING - The protocol is being initialized.

         INOPERATIVE -  The protocol cannot be started because no contact has
 	               been established with the remote station.

         MAINTENANCE -  The logical station is in maintenance mode.

         RESETTING -    The protocol is resetting after an error.

         RUNNING -      The protocol is running and capable of exchanging
                        frames with the remote station.

     REMOTE VERSION

         Version number of the HDLC protocol that the remote station is using.
 	This is received as part of an XID message from the remote station.

     STATE

         State of the logical station.

         OFF - The logical station is off because of a disable command.

         ON  - The logical station is on because of an enable command.
