NXProxy a "root" class that represents a remote object *Object* NXConnection manages a connection between remote objects Phone Kit + =========== The Phone Kit offers an easy way for a developer to connect an application to a telephone line, to initiate and receive calls over the line, and to transmit and receive data during a call.
