Abstract

A method of enhancing communication among a plurality of communicating devices in which an interface comprising a list of features for enhancing the ability of devices to communicate is copied from a device controlling communication to the controlled communication devices. The interface may be a variable portion of a communication protocol that, together with a static portion of the protocol provided separately, defines the communication capability of the devices. The method finds application in telephone systems where the controlling device is a public or private telephone exchange and the controlled devices are computer operated telephones. The display screen of the computer at each telephone may be used to select features of the interface that are to be used.
