Initiates an XID test between the node specified and the node
    specified by the client.

    test  [node node-id] mop client client-name [optional arguments...]

    The Address and Circuit information is required.  If that
    information is not specified in the MOP client database, then it
    must be supplied in the command:

    test [node node-id] mop client client-name -
            circuit circuit-name, -
            address lan-address  [,optional arguments...]

    The optional arguments for the test command are:  count, format,
    length, and sap.

    Examples:

    test mop client lamchp     ! Client gives the Address and Circuit

    test mop client lamchp -   ! Client gives default Circuit
          address 08-00-2b-45-77-ED

    The test requester function must be enabled on the MOP Circuit
    to perform the test operation.  You may enable this function
    using:

    enable mop circuit circuit-name function {test requester}
