AVR-Chat

First off, I'm not sure about your configuration.  When you say the 
transmitter is connected to the computer's serial port and the receiver is 
connected to the AVR, what kind of transmitter and receiver are you 
using? Do you mean RF transmitter and receiver?  What frequency? Have you 
verified that they are working together? What kind of program are you 
using in the computer to generate the baud rate? Are the sending and 
receiving ends both set for the same baud rate/parity/stop bits?
