And the RS-4xx standards (e.g. RS-422, RS-423, RS-449) are even more broken
than the RS-232C standard.  Would you believe a 39-pin plug with an
additional optional 15-pin plug?  This is not a joke.

The reason we have no standards better than RS-232 is because the
people who tried to produce one screwed it up royally, so nobody
followed it, and each manufacturer who didn't do RS-232 (IBM, Apple,
etc) invented something random that was convenient for them.
