The time required to perform a polling sequence for I/O devices connected to an IBM Series/1 processor I/O channel bus is substantially reduced by reducing the time period T between the issuance of the poll identification (ID) code and the issuance of the poll tag signal by the processor. This increases the I/O data rate and reduces the interrupt service time.
