Abstract
A system and method for detecting and handling spurious input are disclosed. In one embodiment, upon receipt of an interrupt signal, a device activates command and keystroke timeouts. The keystroke timeout may have a shorter duration than the command timeout and may be reset upon receipt of a keystroke. At the first expiration of either the keystroke or command timeouts, the device generates a user message. At the second expiration of either the keystroke or command timeouts, the device resumes initialization or resets.
