RS-232 quick tester
No PC interface has attracted more attention in the electronics press, and caused hotter debates, than the RS-232 interface. It is unfortunate but true that both hardware and software appear to be open to different interpretations when it comes to connecting RS-232 devices like printers, plotters, mice and modems. The tester described here is a handy tool to help you locate possible hardware errors, when hooking up a new RS-232 peripheral is not going as smoothly as you would have hoped.
