Many devices have had a serial port for attaching a console of some
sort, for low-level configuration/diagnostic work.  While very simple
to implement, serial ports have issues which don't need repeating.

An obvious alternative is to implement the "serial console" as a
TELNET server.  Conceptually this is trivial, not to mention well
standardized and well understood.  OTOH, this piles on a fair bit of
complexity, and requires something akin to a full TCP/IP stack.  And
if you're going to do that, you might as well just go for a web-based
admin, it's only going to be a bit more work.

OTOH, it's clear that a number of people have implemented a UDP-based
protocol for handling the sort of things often done with a serial
console attached to a device.  This has a number of advantages - you
can fake UPD over Ethernet with very little code, especially if you
define away things like fragmentation and options.  A simplified
TELNET-ish protocol on top of that would be pretty simple, you just
need some basic packet sequencing and acknowledgements. IOW, something
with a relationship to TELNET sort of like TFTPs relationship to FTP.

OTOH, despite looking, I just don't see any standards for doing that
sort of thing.  Am I just missing it?  Is there a defacto standard
even if there's no RFC?
