Abstract
A data processing system operating in a bit oriented protocol (BOP) mode of operation senses a transmit underrun; that is, the subsystem is not receiving data from a microprocessor fast enough to maintain the synchronous transmission over the communication line. Apparatus senses the transmit underrun state and generates an abort sequence of bits containing from 8 to 13 successive binary ONE bits.
