still, that occasional use case is catered for with a USB breakout board, or a USB to serial. So it's not like we have really lost anything

- MBCook 12y agoIt doesn't always work. I've seen serial devices that are so picky with timing that they'll work with real serial ports but most USB->Serial adapters cause programming to fail.
- joezydeco 12y agoAnd let's not forget the 80% of USB->Serial adapters that are using counterfeit FTDI chips and barely work at all, if you can get an O/S to recognize it.
- throwketchup 12y agoExcept for the "reasonable rate" bit, which (IMHO) also includes "reasonable latency." Real UARTs can be used for, e.g., pulse-per-second inputs from GPS or atomic clocks to discipline an NTP server. That doesn't work for a USB->serial thingy (because the latency is literally three orders of magnitude worse).
