Abstract

A communication apparatus comprehensively displays external equipments connected its own station and a destination station. A control CPU 26 repeatedly examines the presence or absence of the connected external equipments and the signal input status from the external equipments by a video input/output circuit 12, an audio input/output circuit 16 and a digital data input/output circuit 20 and stores that information in an internal status flag memory. Similar information from the destination station is also stored in the status flag memory. The available external equipments are displayed by icons on liquid crystal displays of a drawing tablets 64 and 66 in accordance with the information stored in the status flag memory.
