The method also includes the step of (b) evaluating the received message to determine whether the received message was received by the receiving module in a proper sequence to a previous message, if any, sent by the transmitting module. The method further includes the step of (c) generating an acknowledgement message from the receiving module to the transmitting module, the acknowledgement message including an indicator, a value of the indicator indicating whether the previous message, if any, transmitted from the transmitting module to the receiving module immediately before the received message was received by the receiving module.
