The RS-232, or Recommended Standard 232, is a serial communication protocol introduced in 1960 by the now-defunct Electronic Industries Association (EIA). If you're of a certain age and grew up with ...

Before 2000, desktop printers for business had one of two interfaces: serial and parallel. The type of interface dictated the type of cable you used to connect the printer to the PC and how fast the ...

The project illustrates the use of bit-banging on a 12F683 device by the PS/2 interface which can come from the mouse or keyboard with the other side of PCB having RS232 serial interface while being ...

I know, RS-232 is not gone completely but in most things it has disappeared. Recently I bought a new laptop to use in my ham shack. I have several older accessories that use RS-232 and I had hoped to ...
