ABSTRACT:
A method for implementing data communication between a host computer and a remotely-located processor peripheral device is disclosed. A remotely-located processor in control of the peripheral device receives a lists of descriptors or commands for constructing a list of descriptors from the host computer, determines differences between changes made to the lists of descriptors stored on the host computer and changes to the lists of descriptors stored on the remotely-located processor. Changes are made to the lists of descriptors on the remotely-located processor to eliminate the determined differences reflect the changes made to the lists of descriptors stored on the host computer; these changes are sent back to the host computer and the remotely-located processor operates the peripheral device by traversing its lists of descriptors and executing commands that correspond to the descriptors in the lists.
