"still alive"? You mean, something like this:
https://angband.pl/tmp/serials.jpg I assembled just a week ago.
No one bothers making a single-board computer _without_ serial anymore.
On x86, it's also a must if you do any sort of kernel debugging: netconsole
doesn't work if you run a bridge, containers, VMs, your network card was
designed during a different moon phase than the motherboard, or the
planetary alignment wasn't right during their manufacture. And USB console
(on the debuggee's side) is the first thing to go down during a
crash/suspend/resume.
But it's inadequate for connecting a mouse. Perhaps could be made adequate
with some better protocol design, but this ship has sailed.
