more objects:
A. Host Initiated

3. L,i i = identifiers of object instances
requested

Exception: If OBJSPEC is zero-length item, no object specifier is provided. If i = 0,
only the filter is to be applied. If q = 0, no filter is specified. If both i and q = 0,
information for all instances of the objects are requested. If a = 0, all attributes are
requested.
Note that object qualifiers are not currently supported. If any are specified they will be
silently ignored.
