A method for processing software instructions in an emulated computing environment is provided in which instruction blocks from the application programs of a guest computer system are parsed to determine whether the instruction blocks include instructions executable at user level or supervisor level. A voltage is applied between both of the electrodes to generate arc discharge at the notch of the insulating plate. Pressure sensors are provided to sense a source pressure representative of the fluid pressure between the source of pressurized fluid and the electro-hydraulic valve arrangement and an actuator pressure representative of the fluid pressure between the electro-hydraulic valve arrangement and the actuator. A wiring block may also be disposed within the body, and the modular wiring block may be coupled to the terminal. While the receiver on the endpoint is activated, the endpoint may receive a command from the remote device without being required to transmit an additional standard meter reading message.
