I am working on creating an IR remote for an older TV using my GPIO, primarily using this tutorial http://www.raspberry-pi-geek.com/Archive/2015/10/Raspberry-Pi-IR-remote#article_l1. However, when I get to the step that says
sudo /etc/init.d/lirc restart
I can't do that because that file does not exist. lircd and lircmd both exist, but as far as I can tell, they're not a replacement for lirc? If I don't need lirc, what do I need to change to use the lircd or lircmd functions instead?
Eventually, this is giving me a "hardware does not support sending" error with the command
sudo irsend SEND_ONCE Vizio KEY_POWER
I am using a Raspberry Pi 3B+
