| Aug 26, 2018 at 20:31 | comment | added | tofro | RS-485 is not electrically-compatible with RS-232. RS-485 uses differential signals and requires the line drivers to be able to go high-Z in order to be able to use single-line half-duplex transmission and multipoint connectivity. The older Mac's serial port was actually an RS-422 port. | |

While video terminals generally didn't need handshaking at that time, printers, modems, multiplexers and many other devices still used handshaking quite a bit. | |
