Abstract

A network includes a plurality of computer systems interconnected by a plurality of communication links. At least one of the computer systems includes a resettable computer and a reset circuit. The reset circuit is actuable in response to the receipt of a message containing a received reset code value for generating an interrupt signal and to begin a timing interval, and at the end of said timing interval to generate a reset signal. If the computer is in its normal operational condition, it is responsive to the interrupt signal from the reset circuit to deactuate the reset circuit prior to the end of the time interval to prevent the reset circuit from generating the reset signal. On the other hand, if the computer is in the hung condition, it does not respond to the interrupt signal, and so the reset circuit at the end of the time interval will generate the reset signal to enable the computer to initiate a reset operation.
