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. -tim On December 12, 2018, Linux for blind general discussion wrote: > Can raspberry pi's do serial connections?
