Creates an HDLC Link.  The Name of the HDLC Link you wish to create is
    a required argument.

    The profile is an optional argument.  It is a latin1 string of
    information that can be used when the HDLC protocol is dependent on
    network subscription time commitments pertinent to the Data Link layer.
    When specified, the values of some link characteristics may be
    overridden. This argument determines the value of the profile
    characteristic. The default value of this argument is a null string,
    meaning that no profile is used.

    The Link Type specifies the operational mode of the HDLC link,
    determining how the logical station operates. This value is negotiated
    with the remote station.  This argument determines the value of the link
    type characteristic.  Select the appropriate radio button:

    Balanced    The logical station operates in asynchronous response
                balanced mode. This is the default value of the
                argument.

    Primary     The logical station is the primary and operates in
                normal response mode.

    Secondary   The logical station is a secondary and operates in
                normal response mode.

    Press CONTINUE to create the HDLC Link, or press CANCEL to cancel
    this operation.  In either case, you will return to the main window.
