However, binary thresholds of the RS-232 standard, and safety measures in the Mac's buffers permitted both directions to work flawlessly. | |

| Sep 8, 2021 at 18:28 | comment | added | Solomon Slow | Re, "RS-422," "RS-423," Buffer circuits that convert between RS-422 low-voltage differential signalling and the higher-voltage, single-ended signals of RS-232 are widely available. Google "rs-232 to rs-422," and you'll find dozens of them. | |
