Just do the math...

9600 baud (= bit/second)

8 bit data, 1 start bit, 2 stop bits = 11 bits.

9600 / 11 = (aprox) 870 char/sec.
(A little more if using 1 stop bit...)

8 Mhz = 2.000.000 cycles/second.
2.000.000 / 870 = (aprox) 23.000 cycles / character.

And guess what ?
This works, not only with letters, but any 8-bit character !! :-)
