Abstract: Techniques for configuring network parameters to a device are disclosed. In an embodiment, the device is a service processor that provides administrative capabilities to another device and that does not include a terminal. The network parameters include a network address, and configuring is done over a network. A user, from a configuring machine, sends a packet including the to-be-assigned address and the identifier of the configured device to the network. To acquire the packet and thus the address, the configured device regularly checks the network for the packet having the device's identifier. Having acquired the address, the device configures itself, and, to confirm that the address has been configured, the device generates a response to the configuring machine. Once the device is configured with the address, the device disables the automatic configuration feature until the device is in an un-configured state.

Abstract: Data entry apparatus comprising a display screen device, a touch pad mounted over the display screen device, and an application processor coupled to the touch pad and to the display screen device. The application processor has an application program processing module and a touch pad controller module. The application program processing module displays on the display screen a predefined data entry screen having a prearranged set of functional components and sends to the touch pad controller module a hot spot command defining a plurality of touch pad hot spots corresponding in area and location to the set of functional components. The touch pad controller module senses a touch event on the touch pad corresponding to one of the touch pad hot spots and sends to the application processor a touch event message identifying the touch pad hot spot corresponding to the touch event.

Abstract: A method for operating a combination touch pad and display screen device as a PINpad for entering a A plurality of numerical keypad layouts for the display screen are defined. Each keypad layout has a unique arrangement of decimal number locations differing from one layout to all others. For each PIN entry event a random one of the numerical keypad layouts is selected and displayed on the display screen.

Abstract: The present invention, in various embodiments, provides techniques for configuring network parameters to a device. In one embodiment, the network parameters include a network address, and configuring is done over a network to eliminate the requirement of physically attaching a terminal to the configured device. At configuration time, the device is connected to a network having a configuring machine, A user, from this configuring machine, sends a packet including the to-be-assigned address and the identifier of the configured device to the network. To acquire the packet and thus the address, the configured device regularly checks the network for the packet having the device's identifier. Having acquired the address, the device configures itself, and, to confirm that the address has been configured, the device generates a response to the configuring machine. Once the device is configured with the address, the device disables the automatic configuration feature until the device is in an un-configured state.
