What does a keyboard need a receive line for? I thought it's just
unidirectional, transmitting. Or are you referring to the other (Archos) end, where
it's called receive?

I hooked some strange things to the remote pin of the JBR: infrared
receiver, car stereo:
The RX pin has an internal 1K pullup to 3.3V. So if you want to power your
peripheral from there (like I do with the IR receiver), you must not draw more
than, say, 1mA. Some boxes are rumoured to have weaker pullups, makes it
difficult to power from there. After all, the Archos cable remote uses a button
How much does your keyboard draw?
