Essentially every modern x86 SoC has at least one; usually
several.  They may or may not be lined out, but they're there.

Some other systems may use 16550-compatible parts as well; as I
mentioned, DesignWare markets one as an embeddable piece of IP
that one can incorporate into one's own design.

I did not say that other systems used 16550, I was disputing the
incorrect statement that "16550 UARTs are long obsolete."  If
you mean discrete UART chips signaling at TTL levels, whether
shifted to RS-232 levels or not, you're correct, but I took your
statement to be more general.  Simply, they are not obsolete at
all, and they're extraordinarily common.

Ok, but your personal experience is anecdotal and by your own
admission not representative of large machines.  Judging that
the obsolesence (or not) of a part based on your own experience
alone is not a great way to make judgements about these things.

>Of course all these UARTs can /talk/ to 16550 UARTs,

Yes, that's the whole point of a serial protocol between
disparate systems.  :-)

If you go back and re-read Scott's statement, he said modern
systems are usually using a 16550 or a PL101-compatible UART.
That's true; ARM and x86 parts are extraordinarily common.

Of course, there are and have been others; I've personally
worked with Zilog and Motorola parts in addition to the
aforementioned two.

Again, extrapolating from your own personal experience to other
areas is leading to a specious conclusion.  You hinted at the
issue: _if_ your systems can keep up, you may be ok.  But on a
large system, running a multiuser multitasking operating system,
doing a ton of IO on high speed devices, dealing with many
thousands of interrupts a second across many cores, you may not
be able to keep up.
