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
                                 both either end can initiate
                                 connections.  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 characters    Specifies the hexadecimal string that
   Data          (hexadecimal)   identifies the type of X.25 to be made
                                 to create a QLLC connection. The
                                 default value is hexadecimal C3 (QLLC
                                 protocol).

   Remote DTE    DTEaddress      Specifies the X.25 DTE address of the
   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.
