Mmm, true. But then, many - probably most - keyboards don't send letters at all; they send scancodes of some sort. As far back as early Suns, at least, and probably farther, keyboards were sending small integer keycodes bearing no particular relationship to the values of the key-top characters in any character set, even if you consider just the character-generating keys. And of course there are things like electromech teletypes where the boundaries between the keyboard and the rest of the device are not nearly as well-defined as they are with a peecee - or a Sun-3 or a VT-100, which for these (very restricted) purposes are the same as a modern peecee. (Does a purely mechanical typewriter - remember them? - have a keyboard that sends letters? Or does it "send" an index value into the (mechanically stored) array of glyphs in the printing part of the mechanism? Is it fair to consider that index an encoded letter? Some interesting philosophical questions lurking.) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
