Tim here. The RPi has built-in serial pins, but they only output
3.3V, not the 12V required for RS232. There's a good summary here:
https://elinux.org/RPi_Serial_Connection
but the short summary is that, if the other end (the PC) can handle
the 3.3V communications, then it's easy with a couple parts. But if
the other end requires RS232, you also need a level-converter circuit
to do the signal-boosting.
