There is no any misreading. I really mean RPC, since I interpret it
as the protocol of dialogue between Client and Server, i.e. sequence
of inquiry and answer. Besides, USP supports some more then dialog.
Events, it is packets, generated by server without client's inquiry.
Events are notifying clients about status/mode/data changing.
USP allows packing and transferring any information as well. But it
describes not only the format of RCP; USP also regulates the unified
format of data representation. Thus application can unpack and
represent answers of any USP-based protocol to the user or store
them to object-oriented database. This format of data representation
is readable (it is similar XML but short-spoken). It is possible to
describe any objects and data with its help. The unification of data
representation is another degree of unification and protocol's
integration than unification of call/response only. Besides one USP
server can share some affiliated protocols and the client can switch
between those sub-protocols as between interfaces. In this case
saying "interface", I mean set of functions.
