ABSTRACT:
A general purpose communications processor for communicating data between an asynchronous data terminal and a synchronous data communication facility, includes (I) a transmit module, having (a) a transmit processor, (b) an input serial communication controller, for receiving a serial asynchronous data input from the data terminal, and stripping start and stop bits from each received byte, (c) a transmit buffer, operatively connected to the controller, for temporarily storing the data, (d) an adder for adding at least a control byte to the data, and (e) an output serial communications controller for outputting the data and control byte to the synchronous data communication facility; and (II) a receive module, having (a) a receive processor, (b) a second input serial communications controller for receiving a synchronous input from the synchronous data communication facility, (c) a receive buffer, operatively connected to the second input controller, for temporarily storing the incoming synchronous data bytes, (d) a framing circuit for adding start and stop bits to the synchronous data bytes, and (e) a second output serial communications controller for outputting the data to the asynchronous data terminal.
