- Actually, 2400 baud full duplex "only" eats up 40-50% of the avalible CPU
- time on the 64. It's putting it on the screen that eats up the rest of the
- time. :-) 2400 baud in 40 columns is trivial, in 80 columns it gets hard.
- I've seen a 64 do 4800 full duplex in 40 columns -- I think that's really
- the limit for a 64 w/o a Swiftlink. Of course, 9600 single duplex it
- readily doable too, if you're just dumping something to a printer.
