Abstract
A data communications system for asynchronous communication having at least two data transmit/receive terminals wherein the display is periodically updated with new send or receive data. In the receive mode the data is accumulated in a receive buffer for a predetermined time interval and then transferred into a text storage buffer which then activates a display access method to process the stored data and update the display. The display access method then goes into an "idle" mode and waits for the next transfer of data which does not occur until the predetermined time interval has expired. In the transmit mode the send data is transmitted without a delay but the display is updated after the predetermined time interval has expired.
