Usage Type     outgoing |     Specifies the type of connections that
                  incoming |     can run over this station. If set to
                  both           incoming, then only IBM initiated X.25
                                 connections are allowed. If set to
                                 outgoing, then the Peer Server will
                                 initiate connections. If set to both
                                 then either end can initiate connec-
                                 tions.  The default is outgoing.

   Retry          (0-255)        Specifies the maximum number of times
   Maximum                       to retry when an error occurs. The
                                 default is 4.

   Retry           (1-600)       Specifies the time in seconds to wait
   Timeout                       between retries. The default is 10.

   Contact         yes | no      Specifies whether the secondary
   Terminal                      station awaits receipt of a QRR command
                                 or of the first data frame before
                                 establishment of the link connection is
                                 acknowledged. The default is no.

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

   Call User       2 chars       Specifies the hexadecimal string that
   Data            (hexa-        identifies the type of X.25 to be made
                   decimal)      to create a QLLC connection. The
                                 default value is hexadecimal C3 (QLLC
                                 protocol).

   Remote          DTEaddress    Specifies the X.25 DTE address of the
   DTE Address                   remote station. If the Peer Server
                                 initiates the connection, this is the
                                 address that will be called. For an
                                 IBM initiated connection, if
                                 the Usage Type parameter is set to
                                 Incoming, this address will be matched
                                 against the caller's address and if not
                                 matched, the call will be rejected.

   Maximum BTU     (128-4095)    Specifies the size that SNA messages
   Size                          will be segmented into before being
                                 sent to the X.25 network. (The X.25
                                 network may further segment packets
                                 based on the level 2 profile
                                 information being used.)
                                 The default is 512.
