Patent ID: 7991351

Claim:
A method of transferring a message from an originating node of a wired network to a target node of a wireless network, comprising: receiving the message from the originating node of the wired network with an extension module coupled between the wired network and the wireless network, acknowledging the message on the wired network by forcing an acknowledgement bit of the message to a dominant state, in response to the extension module determining the message has been successfully received by the extension module, to indicate successful receipt of the message by the extension module, transmitting the message from the extension module to the target node of the wireless network, waiting for a first acknowledgement message from the target node of the wireless network that indicates successful receipt of the message by the target node, transmitting a second acknowledgement message from the extension module to the wired network in response to receipt of the first acknowledgement message, and receiving with the extension module an acknowledgement of the second acknowledgement message that indicates the originating node successfully received the second acknowledgement message.
