A multilevel communication structure controls input/output (I/O) data transfers and control functions in a computer system. Communication is achieved through shared memory structures in main memory commonly connected to each processor and each I/O adapter in the system. The levels of the communication structure are for communicating information between adapters or processors and processors, for communicating information relative to I/O control functions of an I/O device, and for specifying I/O functional operations. The information contained in the memory structures may be directly interpreted by sequencers of the I/O adapters, to achieve the I/O data transfers.
