Things Every Hacker Once Knew
This document is a collection of facts about ASCII and related technologies, notably hardware terminals and RS-232 and modems. This is lore that was at one time near-universal and is no longer. Itís not likely to be directly useful today - until you trip over some piece of still-functioning technology where itís relevant (like a GPS puck), or it makes sense of some old-fart war story. Even so, itís good to know anyway, for cultural-literacy reasons.
