    https://en.wikipedia.org/wiki/Acknowledgement_(data_networks)#Hardware_acknowledgement The ACKNOWLEDGMENT message
    https://en.wikipedia.org/wiki/Acknowledgement_(data_networks)#Protocol_usage
12. acknowledge character An ASCII code or a special code sent from a receiving terminal after receiving an enquiry character to indicate that the receiving terminal is operating normally, or sent by a receiver to indicate that the transmission has been received correctly and is ready for the next transmission.

14. acknowledgement A message, or signal which sent by receiver to show that the transmission has been received correctly and the receiver is ready for receiving another transmission.
    https://en.wikipedia.org/wiki/Acknowledgement_(data_networks)
15. acknowledgement message A message sent from a receiver to indicate that the transmitted message has been received correctly, and the receiver is ready for receiving next transmission, or the receiver is in normal operating condition.
