Linux Infrared Remote Control

LIRC is a package that allows you to decode and send infra-red signals of many but not all commonly used remote controls.

The most important part of LIRC is the lircd daemon that will decode IR signals received by the device drivers and provide the information on a socket. It will also accept commands for IR signals to be sent if the hardware supports this. The second daemon program called lircmd will connect to lircd and translate the decoded IR signals to mouse movements. You can e.g. configure X to use your remote control as an input device.

The user space applications will allow you to control your computer with your remote control. You can send X events to applications, start programs and much more on just one button press. The possible applications are obvious Infra-red mouse, remote control for your TV tuner card or CD-ROM, shutdown by remote, program your VCR and/or satellite tuner with your computer, etc.
