lk401 keyboard protocol?

Even if it has buttons that produce characters not present in ASCII? (I've personally seen at least one such.) Michael, I greatly respect your technical competence. But you really need to tone down the zealotry, especially where it runs counter to the way the rest of the known world does things, or you will be - deservedly - marginalized for it regardless of whatever else of value you may have to offer. Perhaps that prospect doesn't bother you. Perhaps being Pure matters more than communication with other people. In that case, go right ahead. But I, for one, will then soon be mechanically ignoring you. Do you actually know anything of the history of alphabetic writing? Do you know how utterly insane it is to try to consider ASCII primal, when anything significantly similar to the English alphabet is a relatively recent innovation? This stance is not even logically defensible, because it leaves no place for symbols that do not have ASCII codepoints, yet the only difference between (say) a handwritten A and a handwritten symbol of comparable complexity with no codepoint is that one has more widespread cultural and linguistic recognition and utility than the other. It also runs into problems where a single graphic symbol may correspond to various codepoints. (I'm thinking in particular of the line-and-two-arcs drawing typically read in English as a `B'. It could be any of at least three and probably more semantically distinct characters: think English, Russian, and Greek. For that matter, in the right context it could even be the number thirteen.) Well, exactly what the keys generate doesn't matter (and indeed the LK201 doesn't generate ASCII either; that's a mapping performed by host software). I just want software to be able to distinguish between what on the LK401 are the left and right ends of those keys. I don't remember the VT100 keyboard well enough to say how close this is to that. As I said, it's a matter of what I'm used to. The LK[24]01 isn't it. /~\ 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
