ABSTRACT:
A receiver for receiving packet data from a transmitter, the transmitter and the method of controlling transmission. The receiver may comprise first detection means for detecting that its memory has enough space to store a data packet and flow control signal means for providing a flow control signal, preferably a first flow control signal, to the transmitter in response to said first detection means. The receiver may comprise second detection means for detecting when a first portion of a packet has been received from the transmitter and flow control signal means for providing a second flow control signal to the transmitter in response to said second detection means. The transmitter may comprise third detection means for detecting the second flow control signal sent by the receiver and packetwise transmission means arranged, responsive to the third detection means, to complete transmission of a partially transmitted packet and then to stop transmission of further packets.
