: Just a minor nit to pick here - there's no such thing as "baud/sec".
: Baud rate is given in baud, which is the information transfer rate
: in SYMBOLS per second.  You can properly refer to a "2400 baud"
: interface, but NOT a "2400 baud/second" interface.
Very minor nitpick, Baud/sec is a valid unit, meaning rate of change of
changes per second. Perhaps usefull in continuously variable speed modems
response to noisy lines?
