Apparatus for optically indicating the status of data-communications terminal equipment, such as a modem. The description is confined to a pair of two-colour LEDs (green/red), each of which may be "on", "off", or alternating between "on" and "off". One LED displays the status of the telephone connection, the other one that of the computer having the data-communications terminal equipment. <IMAGE> |
