The code seems right.Thing you may have to check:. if your baudrate is the one you should have. if you try to send a char like 'p'; now you are sending a '+'. check your port configuration and see if it matches to your configurationI think the last one is the problem.You can try this code from ATMega manual: /. Set frame format: 8data, 2stop bit./UCSRC = (1. Your FCPU is set to 10MHz.you sad that it is configured to 1Mhz.Also check your Fuses if you really activated the crystal.If you just use the internal oscillator: it has a relatively large error so that your UART timings may be broken (i never got problems using internal oscillator for debugging).Another source of error may be your FCPU definition. Mostly this Preprocessor constant is defined already (propably also wrong) in Makefile (or in IDE project settings) so your #define in Code has not affect since the #ifndef.

Hello Aviraje,Firstly sorry for delayed reply.As I understand, you are trying to code with WinAVR or AVR studio.Please download 3 PDF files from following drop-box link.note that, I've LEDs connected to PORTB and UART connected to PC.Now, when you enter a digit on HyperTerminal corresponding digit will turn on LEDse.g if you enter 9 on HyperTerminal means 0000 1001 (in BIN), this will turn on LEDs connected to PB0 and PB3.I hope this will help you.Regards,Kaustubh Ghaisas.
