This seems to be a requirement to drive some printers... The super-serial chips, or whatever they are called (it's late, alright?) are not supposed to run any faster than 38400, or so I've heard. The problem is mostly that they are simply older technology (albeit well-proven). I've heard various rumors about various devices that _can_ go faster - via the SCSI or DPS ports - but, alas, as shipped Unix can't do greater than 38,400. I doubt there are any printers with such limits. They'll probably run faster at that speed, but they probably don't _require_ it. The reason being that NeXT's serial io is as good as most PCs, which means that it's probably capable of accepting lower speeds. Would seem sort of stupid not too, I'd think . . .
