Abstract: A data processing apparatus is provided comprising first processing circuitry. Interrupt generating circuitry generates an outgoing interrupt in response to the first processing circuitry becoming unresponsive. Interrupt receiving circuitry receives an incoming interrupt, which indicates that second processing circuitry has become unresponsive, and in response to receiving the incoming interrupt, causes the data processing apparatus to access data managed by the second processing circuitry.

Abstract: A modem is incorporated into a laptop computer and directly connected to either a cellular phone, a land line, or both. The modem is provided with two connectors, one for connection with a cellular phone or external DAA, the other for connection to a normal land line via an internal DAA. The modem selectively enables either the connector for the cellular phone or external DAA, or the connector for its internal DAA. The modem defaults to selecting the cellular phone or external DAA if it is connected, and only if they are not connected selects the internal DAA. These defaults can be overridden by user commands. Further, the modem can independently power down a connected internal DAA, external DAA, or cellular phone to conserve power.

Abstract: A modem which includes connections for both land lines and a cellular phone. The modem contains high and low level routines that allow it to perform standard AT commands rationally when connected to a cellular phone, and further perform additional AT commands that access cellular specific features. An applications software program in a computer connected to the modem can provide a number of options for determining whether to use the land line or the cellular phone when both are connected. First, it can default to the land line and only use the cellular phone if the land line is not available. Alternatively, it can first use the cellular phone and only use the land line if the cellular phone signal strength is not sufficient. Further, cellular file transfer operations can be aborted if the remaining battery life in the cellular phone is insufficient to reliably complete the transfer.

Abstract: In a microprocessor system including arbitration for an interrupt, an apparatus and method for monitoring the arbitration lines to determine whether an interrupt request is real or spurious is includued. Once an interrupt acknowledge signal is provided, the interrupting apparatus must arbitrate for the interrupt slot. If no arbitration occurs the interrupt request was spurious and bus error is activated.

Abstract: A new and distinct cultivar of dwarf Bermuda grass, named RJT, is described and illustrated herein. The cultivar is characterized by its very fine texture when closely mown, the retention of its fine texture at higher heights of cut, its low nutrient needs, its very low thatching characteristics as compared to other dwarf Bermuda grasses, and its prolonged proven stability against mutation.
