Initiates an XID exchange between the system you are managing and the
    system specified by the LAN Address below.  If you optionally
    chose to enter a Client Name in the previous menu, the default query
    parameters for this operation were obtained by looking up the
    information for that MOP Client, and those parameters are present in
    the current display.

    The required arguments for this query operation are:

     o  Address

        The LAN address of the target node on the circuit named in the
        circuit argument.

     o  Circuit

        The MOP Circuit entity you have currently selected for the query
        operation.

     The optional arguments for this query operation are:

     o  Client

        A client entity to be used for this operation, if you provided one
        in the previous display.

     o  SAP

        An octet representing the Service Access Point (on the target system)
        to which the XID message is to be sent.

    Pressing the OK button will cause the query command to be executed and
    will return control back to the main window.

    Pressing the RESET button will cause all the arguments to be reset back
    to the state they were in when you first entered this display.

    Pressing the CANCEL button will return you to the main window.  No query
    command will be issued.
