[tlinux-users:07469] Re: Infrarred and remote control

You got it!

I noticed that some Linux applications (xmms, mplayer, amarok) have 
plugins for infrared remote control. And there is a infrared port in my 
Toshiba laptop. So, can the signal from a remote control of a tv (of 
Toshiba, by the way) be received by the laptop and used by those 
applications? I have no idea. It may even be impossible (for example, 
signals are incompatible for some reason). However, if this is possible 
it will be really cool for presentations, watch videos, listen music...

If you buy a tv card with remote control or construct a custom serial IR 
port, you can already do those things in Linux (or so the LIRC webpage 
says). My question is, can I use the IR port of the laptop to receive 
the signal from a remote control?

if I find more I will tell you.
