A computer system includes a peripheral device and a processing unit. The processing unit is adapted to execute a driver for interfacing with the peripheral device in a standard mode of operation and an authentication agent in a privileged mode of operation, wherein the authentication agent includes program instructions adapted to authenticate the driver. The peripheral device may comprise a communications device, such as a software modem. A method for identifying security violations in a computer system includes executing a driver in a standard processing mode of a processing unit; transitioning the processing unit into a privileged processing mode; and authenticating the driver in the privileged processing mode. The driver may be adapted for interfacing with a communications peripheral device, such as a software modem.

A communications system includes a physical layer hardware unit and a processing unit. The physical layer hardware unit is adapted to communicate data over a communications channel in accordance with assigned transmission parameters. The physical layer hardware unit is adapted to receive an incoming signal over the communications channel and sample the incoming signal to generate a digital received signal. The processing unit is adapted to execute a standard mode driver in a standard mode of operation and a privileged mode driver in a privileged mode of operation. The standard mode driver includes program instructions adapted to extract control codes from the digital received signal and configure the physical layer hardware assigned transmission parameters based on the control codes. The privileged mode driver includes program instructions adapted to independently extract secure control codes from the digital received signal, determine an operational characteristic of the physical layer hardware unit, and signal a security violation in response to the operational characteristic being inconsistent with the secure control codes.

A computer system employing an interrupt coprocessor is provided. The interrupt coprocessor is signaled by an interrupt controller to service a particular interrupt request. The interrupt coprocessor may include limited functionality, such that if a particular interrupt request is beyond the capabilities of the interrupt coprocessor, the microprocessor is interrupted. Context saves may be avoided in the interrupt coprocessor. Interrupt latency is reduced, as well as interruption of one or more main microprocessors in the computer system. Several embodiments are shown with a range of interrupt servicing capabilities. A data pump is shown, which is configured to transfer data from a source to a destination. A microcontroller is shown, which may manipulate the data as it is moved from source to destination or access the interrupting device to determine the service needed. Finally, a microprocessor similar to the main microprocessors of the computer system is shown.

A system, computer program product and method for automatically restoring logon connectivity in a broadband network system. Upon establishing a connection between a client and Internet gateway (INTERNET GATEWAY), the status of the connection, i. e. , connected or disconnected, may be checked by issuing a request to an INTERNET GATEWAY utilizing a protocol that is normally blocked when the client is disconnected. By issuing a request utilizing a protocol that is normally blocked when the client is disconnected, the status of the connection may be determined by whether the request may be serviced. If the request cannot be serviced, then a subsequent connection may be established automatically by terminating the logon procedure associated with the preceding connection, e. g. , initial connection, and executing the logon procedure associated with the subsequent connection.
