Changing baud rate and clock cycle in Make file does nothing (serial not working mega328)

[JosiahCochran]

okay, first off, I was using an rs323 cable, which I fixed usign an op amp and not gate, but my baud rate is 1200 so there is a devide by 8 set somewhere, but I still cant find out how to change the baud rate. serial loopback now works since I did the data conversion from rs232, but my baud rate is 1200. sidenote, I tried the blink code with the attiny85 and it works sometimes, but most of the time it compleatly fails. could you possibly write something on what needs to be changed to use your code for AVR's other than the168p?

The fact that your baud rate is 1/8 of expected one makes me think that your ATmega328 is running with the default 1/8 prescaler (is it brand new?)

See pages 189-192 for more details.

I read through that section in the book, thatk you! very helpful! I now understand the makefile better and how to actually change fuses and things!
