  • Full duplex conversation between transaction programs
    Patent number: 5051892
    Abstract: A method for the full duplex exchange of data via a conversation between a pair of transaction programs over a network in which any transaction program which requests a confirmation of previously sent data inhibits the further transmission of data until a response to the request is received and a transaction program which receives a request for confirmation will inhibit the receipt of data until a response to the confirmation request is sent. In addition, when a transaction program attempts to terminate a conversation a definite response is requested and the response to the termination will be queued behind any data which remains to be sent so as to purge that data from the network.
