<p>An improved telephone system (1) is controlled by an information processor (20) adapted to receive and transmit signals indicating various operating states of an associated telephone unit (10). Hook information is transmitted such that a distinction can be made between on-hook and off-hook states of the handset (15) of the telephone, enabling automatic logging of calls and automatic registering of telephone numbers in a directory. Data indicating the occurrence of data communication on the data network (4) is transmitted, enabling voice communication on the network (4), which would interfere with the data communication, to be inhibited. Data indicative of the charging state of a battery (132) associated with the system, and/or the presence of unread electronic mail, is transmitted enabling these factors to be checked without the need for powering-up of the information processor (20) or runnning of special software. The latter data may be used to activate LEDs (51-53). The information processor (20) may include a combined display/touch screen data entry device (111). <IMAGE></p> |
