Abstract: A device driver is configured to provide access to at least one peripheral device through a normalized interface. A loader is provided with the device driver. When the loader is executed, the loader loads the device driver to an operating system (OS) within its own independent processing context. The interactions through the normalized interface are OS independent.

Abstract: An Inter-Process Communication (IPC) message transport mechanism is provided with an Application Programming Interface (API). Applications use the API to create and register clients, and device drivers for devices use the API to create and register services. The applications and device drivers use their own independent API to pass commands and responses to one another using the clients and services. An IPC message transport manager manages and routes the commands as messages without any restrictions on the format or content of the messages. The messages routed in an OS independent fashion.

Abstract: A fault replay system uploads part or all of a log file from a subject system and replays the events detailed within the log file upon physical copies of devices present in the subject system. The replay of the log file events aid the determination of at which event a fault occurred and improves the accuracy of fault determination.

Abstract: A method of using a mini filter driver to secure access to encrypted information stored on a removable storage device. The method comprises receiving a request to read information from the removable storage device. The mini filter driver ascertains if the request originated from an authorized client. The mini filter driver receives encrypted information read from the removable storage device, and decrypts the encrypted information in the event that the request originated from an authorized client. The decrypted information can then be conveyed to the authorized client. If the client is not authorized, then the mini filter driver does not decrypt the information.

Abstract: A method of operating a self-service terminal is described, along with software for performing the method. The self-service terminal has a number of service providers installed on it. According to the method, a call from a self-service terminal application to open a session with a service provider is received by a manager module. The call includes details of a device related parameter, such as a logical service name or device class. Those service providers which can support the device related parameter are identified and then queried to determine if an associated device is present. Based on the results of the query, one of the service providers is selected and a session is opened between the self-service terminal application and the selected service provider module.

Abstract: A method of managing code-tracing data is described. The method comprises the steps of: receiving code-tracing data from an executing software component; adding the received code-tracing data to a log stored in temporary storage; detecting a property of the received code-tracing data; copying the log to non-volatile storage when the property matches a defined trigger property; and deleting contents of the log according to a caching policy when the property does not match a defined trigger property.
