Abstract

In the prior art, a demand/response interface required a one-to-one correspondence between the command sent across and the setting of incomplete status. The use of encapsulated (multifunction) commands and incomplete/error status is, without more information, ambiguous, since it does not identify which of the functions cannot be completed. The method described below seeks to resolve this point.
