Abstract

The terminal device has a network transceiver and a processor having a first program to cause the processor to transmit a packet of data using the network transceiver in accordance with a data transmission protocol. The first program begins transmission of a packet by sending data to a transmit signal input of the network transceiver in accordance with the protocol. At a circuit level associated with the network transceiver, a received signal in the transceiver is detected at a time of sending data to the transmit signal input. In response to this detection, transmission of the packet is prevented.
