A system synchronizes data flow between a first device and a second device. The system includes a data link that connects two or more devices that are capable of sending and receiving data through a bus. A capture device senses and transfer information through the bus. A ring buffer temporarily stores data transmitted through the bus. A read controller copies or reconstructs data in a length that is different from the length of the data received. A monitor detects underflow or overflow conditions into or out of the ring buffer and compensates for clock drift.
