Abstract

A local communication system has a number of stations connected for the communication of messages by one or more data channels. One of the stations comprises a display device operable to display messages (M1, M2) sent by other stations in one or more of a plurality of fields (F1, F2, F3). On receipt of a display command and message the user output subdevice of the display ascertains whether there are sufficient display fields available to display the entire message and, if so, allocates display fields to the message. Messages from two or more stations may be displayed simultaneously if there are sufficient available fields, with the user output subdevice allocating an appropriate number of fields to each message.
