Humor nit:
There is such a thing as "baud/sec", it just isn't what people normally
think of.  Baud means symbols per second, so baud/sec means 

symbols per second per second

or the rate change of the rate of moving symbols (acceleration).

Don't know what the unit is, or where one would use it (probably in a
transciever specification where the baud clock is allowed to change at
some maximum rate or some such)
