Cable VGA vs RS232: utilidad, historia y diferencias. Cable RS232 recto vs RS232 null modem

Hello, very good, welcome to my channel. In this video, I'm going to talk about VGA video cables and RS232 serial cables. I'm going to tell you their history and the usefulness of each one. We're also going to look at the difference in wiring (with the help of a multimeter) between a straight RS232 serial cable and a crossover (or null modem) one, and I'm going to explain what they're used for. I hope you like the video. Feel free to comment. Thank you very much for visiting. See you in the next episode. Best regards. -------------- Hello, welcome to my channel.
