And the RS-232 interface of a PC is commonly referred to as a "serial port"
or "COM port".  In fact, he used both terms and even clarified that they
meant the same thing:

  "of the serial interface (rs232)"

Actually the point is that it's dying, and already dead for a large segment
of potential users.

The OP was concerned about "future proofing" and specifically asked about
USB as a option:

So I pointed him to one way to access USB easily from a PIC.

Many PC users now have notebooks as their only PC.  If he wants to
distribute his gizmo to the general public, then whatever restrictions
notebooks have should be considered.  I don't remember him saying this was a
one-off hobby project for personal use with a well known system.

You need to get a life.
