Abstract
A communication adapter for connection to a modem and a computer terminal between which data is transmitted. The adapter has a first port for connection to the modem and a second port for connection to the terminal. A buffer memory is provided for storing data received at either of the ports. Data is transmitted between the modem and the adapter at a first rate and data is transmitted between the terminal and the adapter at a second, higher rate. The flow of data between the adapter and the terminal is controlled, whereas the flow of data between the modem and the adapter is not controlled. Accordingly data arriving from the modem is initially stored and then transmitted onto the terminal in dependence upon a voltage appearing on a terminal port pin indicating that the terminal is ready to receive data. Data received from the terminal is stored and then transmitted to the modem, a voltage applied to a pin of the terminal port indicating to the terminal when the adapter is ready to receive further data.
