Abstract
This invention is used in a real time system that includes a host processor, interface hardware and an external device controlled by the interface hardware. To maintain system real-time performance, handshake protocol between the external device and the interface hardware is automatic during command execution. This invention moves control of the external device to the host processor if a command doesn't finish before a host processor specified time limit. If command execution exceeds the time limit, the host processor controls the handshake protocols directly and sequentially. This prevents system breakdown caused by trouble at the external device.
