I work on some fancy stuff that the engineers forgot to put serial ports on so I can look at basic processes.
Oh, there are workarounds but wouldn’t it be nice to be able to monitor the boot process on all the processors without the overall OS coming up?
BTW, I had one heck of a time finding a RS-232 to USB program that would work with windows 7 to run my Ten Tec RX320D, but I did finally find one and now it works like a hose.
I remember when UART was a big deal.
Back in the day, I helped develop a UART box that would let you command individual processors in a complex system when the main frames were offline.
