Fully asynchronous /spl mu/C interface serves in a pinch

This two-way interface allows the user to send and receive information between two microcomputers via one-line message displays, with the readout appearing simultaneously at both transmitting and receiving screens. The design of this parallel-line, handshaking interface is fairly straightforward, and it is easy to build and troubleshoot. Thus, it is an ideal first project for the student, or a simple and fast undertaking for the advanced engineer who requires rudimentary communications in a pinch.<
