hi
your code is not right for this application.
you can follow this code to arrive to your idea:
if(UCSRA & 0x80)
    {
        data=getchar();
    }
code written for ATMEGA16.

I saw you "read USART section of your AVR datasheet carefully" and say you again 
, read your AVR datasheet carefully , you will find your answer.

Subject: Re: [AVR-Chat] time of getchar

  
thanks for your help
actually i don't use interrupt
and if it didn't receive data , i want it to skip the getchar command
so can i use

if(getchar()) //instead of if(rx_counter0)
{
ch = getchar();
}
