Connect TX to RX, RX to TX and Ground to Ground.
Setup the UART in each Atmega for the same number of Start, Data & Stop bits. and the same Baud rates.

Now send data from one Atmega and receive the data on the other Atmega.

If you're talking between two Atmegas, why are you using UART?
I2C and SPI are both better protocols for this purpose IMO. I2C is much more flexible, and SPI can run faster (but uses more pins.)
