Abstract

A communication device (1) comprising: a first communication system (4) for transmitting and/or receiving signals according to a first protocol; a second communication system (3) for transmitting and receiving signals according to a second protocol, the second protocol having the facility that a receiver (3) can indicate to a transmitter (2) that it is in an unresponsive state whereby the transmitter can be inhibited from transmitting data to the receiver when it is in the unresponsive state; a signal activity detector (9) for detecting activity in the signals of the first protocol; and a control unit (7) responsive to the signal activity detector for causing the second communication system to indicate that it is in an unresponsive state.
