Is it possible to connect an RCX to an iOS device? I have an RCX and want to know if it's possible to connect it to an iOS device. If this is possible, how do I do it?
Communication with the RCX Brick was via the Infra Red tower (or IR Remote Control) which connected to the computer with either a serial or USB cable.

As neither iPhone nor iPad have an IR port, there's no way to connect directly between the two.

You might be able to do something with a docked iOs device, but that strikes me as somewhat pointless.
