Abstract
A plurality of message packets are individually acknowledged in a communications network. The acknowledgement includes multiple types of status information including ACK, NAK and BUSY. Each message packet is assigned a sequence number. Acknowledgements are sent in response to receiving a message packet and include status information for the last message packet received along with status information for the seven message packets previously received. If after a timeout period expires and no message packets have been received, a status inquiry message is transmitted.
