Abstract
A data processing system includes a number of input/output devices coupled to a communication multiplexer by 1 synchronous communication line and a number of asynchronous communication lines. During the polling operation, receive communication lines have high priority and transmit communication lines have low priority. Apparatus in the polling logic gives the synchronous communication line in the receive mode first priority and the synchronous communication line in the transmit mode second priority.
