I'm trying to set up lirc on a Pi2 B+ running the latest Raspbian buster and latest kernel / firmware set by rpi-update.

I've started from this HOW-TO.

All I get from

sudo modprobe lirc_rpi

is:

modprobe: FATAL: Module lirc_rpi not found in directory /lib/modules/4.19.79-v7+

How do I get lirc to work?

Thanks in advance for your help!

It really doesn't help using a tutorial from five years ago on a modern system. Too much has changed.

lirc_rpi has been replaced by dtoverlay=gpio-ir and dtoverlay=gpio-ir-tx in /boot/config.txt. See https://raspberrypi.org/forums/viewtopic.php?t=243583 for more details.
