Describes the Logical Level 3 (generic level) Interface for tape drives. Facilitates the development and use of an intelligent interface that allows the interconnection of multiple peripheral types to a controller. Gives a definition of the device generic portion of a family of standards called the Intelligent Peripheral (IPI). Coverage includes: definitions and conventions; data buffer operation; normal data operation completion; abnormal position operation completion; tape mark detected
