Abstract

A system for communicating between a channel processor and a device controller processor over a path that includes a parallel bus and a serial link operates according to the IBM OEMI Interface architecture. A serial data frame is sent every time a tag signal changes state on the parallel bus. Due to the nature of the technology used to transmit the serial data, errors occur in the normal day-to-day operation of the serial link.
