ABSTRACT:
An interface circuit for interfacing data communications between two synchronous data terminals over an asynchronous communications channel is described. The interface circuit includes a transmit means and a receive means, both of which operate independently of communication protocols, break or idle codes, synchronization characters, and data frames. The transmit means receives synchronous bit data from a synchronous terminal converts it to an asynchronous character data stream, and asynchronously transmits it at the baud rate of the asynchronous communications channel. The receive means receives the asynchronous character data from the asynchronous communications channel converts the asynchronous character data into a synchronous bit stream and transmits the synchronous bit stream synchronously to the synchronous data terminal.
