As has already been responded by slebetman, that refers to Mac OS 9 and
earlier.

Your main problem on a modern Mac is that it HAS NO SERIAL PORTS.

Well, modern Macs don't SHIP with serial ports, anyhow.

That said, I know there are USB-Serial adapters you can get, and there
may even be usable PCI cards to add serial ports. The answer to your
question then depends on the vendor of said hardware.

For example, a quick google search shows that at least one version of
the Keyspan USB-serial adapter creates something like:

   /dev/cu.USA28X111P1.1
   /dev/cu.USA28X111P2.2

You'll just have to check your specific machine/hardware combo.
