Someone who knows alot abou electrical engineering, physics, and programming

OK, first of all, I am somewhat doubtful that anyone on this board knows the answer, but I'll give it a shot.

I've been working with Palm OS programming, on the GNU palm compiler. I am looking to do neat things with the IR port on the top. Specifically, detect IR pulses, record them, and rebroadcast them at a later time.

However, I don't know enough about the physics behind it. I can work with the high level IR aspects of the device, but they all involve data connections to other devices. The problem being, I want to work in a connectionless manner, like a television's remote control.

So what I am endeavouring is roughly equivalent to building a modem, when all I know is socket programming.

I can point you to all the docs, but I just don't understand how to access the IR port in a very low level fashion, and transmit at a specific..., uh, frequency or whatever. See? I don't even know what factor of an infrared pulse distinguishes it from any other.

Can anyone help me with this?

there's a mailing list at lirc.org that might help you. lirc=linux infra-red control.

Ahh, now my mind hurts.

There are devices which you could use in your device to detect IR pulses. You still need to define and implement a protocol to let everything work. Why do you need physics? Or do you want to build the IR pulse detecting device also?

I have a device with an IR port, but it is designed for high level data connections. I don't know how to just listen for any type of IR pulse and send out a specific pulse. For the physics part, I just need to know what about any single IR pulse makes it different from another.
