	Oh please.  Here we had this issue all nice and put to bed, with all
the oversimplifiers firmly silenced, and then you go and make it all murky
again.  Bits is bits, and BPS is BPS.  I mean, where would we be if everyone
went around dragging the interpretation of the bits into it?  I'll tell
you--people's bit rates would be dropping by 10% on the same hardware, just
because they started sending two stop bits instead of one.  And what about bit
stuffing?  Now the bit rate depends on the data!  Pandemonium.
	You've destroyed the simple, elgant relationship between baudrate and
BPS.  Now we here in the universities will have to spend untold tax dollars
developing a new calculus to explain it to each other, while you industry
people drink coffee and hold barbecues.  I hope you can live with yourself.
