/BUS=(bus1,bus2,...)

    Includes specific buses (LAN devices).  The default is all buses
    included.  Bus names are displayed by the PE BUS command.  Each
    bus name may be preceded by "NO" to exclude the bus.

    /BUS=ALL includes all buses.  /BUS=NOBUSn, equivalent to
    /BUS=(ALL,NOBUSn), includes all buses except BUSn.  /BUS=BUSn,
    equivalent to /BUS=(NOALL,BUSn) selects only BUSn.
