Serial ports can be replaced with USB converters.

Yes and no. Although they work easily for most things, for some pieces
of equipment that you might want to connect to, it can take trying 2 or
3 different converters before you find one that works.

Megasquirt engine management systems are one example, while some PLCs
are another.

Quite. It's used for MS in this workshop. A USB converter works OK between
laptop and MS in the car, but doesn't like the cable runs here.
