Abstract
A fault tolerant communication protocol transmits information across a communication channel from a transmitting device to a receiving device. The receiving device echoes back a copy of the transmitted information to the transmitting device. The transmitting device sends a first valid signal across the communication channel if the echoed information matches the transmitted information. The receiving device sends a second valid signal across the communication channel responsive to the first valid signal. The transmitting device stops sending of the first valid signal responsive to the second valid signal and the receiving device stops sending the second valid signal responsive to determining the first device has stopped sending the first valid signal. The receiving device can then update its state based on a successful transfer.
