RS232c Handshake Lines Transfer Data Frames -  10/23/97 EDN-Design Ideas  The asynchronous RS-232C interface is a simple, low-cost option for interconnecting processor-based systems, but this character-oriented interface supports no direct mechanism to transfer variable-sized messages as self-contained data packets. However, you.... [Design Idea by SK Shenoy, Naval Physical & Oceanographic Lab, Kochi, India]
