[avr-gcc-list] Student Needs Help With GCC Test 7 (UART) and the ATMEGA 128.

I am a student at Point Park College working on
my senior project. I amattempting to use the UART on
the Atmega 128 with an STK500/501 starter kit with no
I have successfully compiled and programmed a
8515 with the GCC test program #7. I have also
compiled and programmed the Atmega 128 with GCC test
When I attempted to compile GCC test program #7
for the Atmega 128, I get a number of errors such
Now I know that some of the register names have
changed because of the extra UART and new functions.
I have changed the uart.c file as follows:
UDR was changed to UDR0
UCR was changed to UCSR0B
UBRR was changed to UBRR0L
I also edited the uart.h file to change the clock
system frequency from 4.0 MHz to 3.69 MHz. This is
the frequency that AVR Studio 3.53 is set at.
The files now compile with no errors but I still
can not get the UART on the Atmega 128 to function.
Does any on out there have any Ideas or some
sample code the would explain what I am doing wrong?
Any information that you can give me will be greatly
appreciated. Thank you for your time and have a nice
