lk401 keyboard protocol?

As may be. Do they not have keyboards? You went off on a long tangent when replying to this and never got around to answering the point. As someone else said, what then are those things with all the buttons labeled with letters &c on them? Your attempt to redefine `keyboard' is perhaps vaguely amusing, but both singularly useless (leaving no word for the devices when they're driven by software that doesn't generate ASCII, or when they're not connected to a computer at all) and contrary to common - universal, I would have said before I saw your redefinition - understanding and use. I do? I don't know where it originated. I also don't much care. Having the buttons there is a Good Thing[%]; nothing compels you to use them in a way you find distasteful (or even at all); if you like, you could even have your software treat all three of them as extensions of the spacebar. What _I_ dislike about the LK401 (and LK201, for that matter) is that the <X] key and the right Shift key are single keys; I want each of those to be split into two keys. You can rearrange keys in software, but software can't give you two keys in a location where there's only one button-and-switch. But that's largely a function of what I'm used to. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
