+** Serial IR Receivers
+This role preconfigures the system for serial "homebrew" receivers. Newer kernel versions provide ~serial_ir~ which acts as a rc-core driver, so we don't need lircd (it works with eventircd OOTB).
+
+As configured in the role yavdr-remote ([[*create /etc/rc_maps.cfg][/etc/rc_maps.cfg]]) a keytable for a RC-6 MCE remote is loaded by default. You can choose a different keymap which may use another ir-protocol.
