USB-C and RS-232C Cabling Frustrations
- Comparing USB-C to classic RS-232C cabling frustrations and diagnostic breakout boxes.
Cable Frustrations
- On June 23, 2025, I compared USB-C to the classic RS-232C standard, noting that both only guarantee that devices won't catch fire when connected, rather than guaranteeing they will actually work.
- I lamented the confusion of modern USB-C cables, such as some being limited to 40W power delivery or 5Gb/s data transfer.
- I shared that I had purchased the modern equivalent of RS-232C "breakout boxes" to diagnose and test these various cables.
