The optional Format argument is an octet (00-FF) which specifies
    the value of each byte in the test data.  The default results in
    alternating 0 and 1 bits (55).

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

    If an Address and Circuit are not supplied by the MOP client
    database, then that information must be provided in the command:

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

    Examples:

    test mop client lamchp -    ! Client gives Address and Circuit
         format FF

    test mop client lamchp, -   ! Client gives default Circuit
         address aa-00-04-00-34-56, format 00
