Abstract
Communication, using a synchronous protocol, over a synchronous communications link, between synchronous application programs executed on a terminal (i.e., personal computer, PC) with an asynchronous byte-oriented interface and a PC with a synchronous frame orientated interface is made possible by enhancing the PC with the asynchronous byte-oriented interface with a device which modifies the data to be transmitted by inserting framing flags and transparency characters before the data passes through the COMM port (asynchronous byte-oriented interface) and extracting the transparency characters after the data exits the COMM port. As a consequence, the PC with the frame-oriented interface does not have to be modified.
