TRY

For example
Board AT91SAM9XE-EK
USART -> baud

const Pin at91board_usart[] = {PIN_USART0_RXD, PIN_USART0_TXD};

int main()
{
AT91C_BASE_PMC->PMC_PCER = (1 << AT91C_ID_US0);
PIO_Configure(at91board_usart, PIO_LISTSIZE(at91board_usart));
USART_Configure(AT91C_BASE_US0,USART_MODE_ASYNCHRONOUS,19200,BOARD_MCK);
USART_SetReceiverEnabled(AT91C_BASE_US0,1);
USART_SetTransmitterEnabled(AT91C_BASE_US0,1);
USART_Write(AT91C_BASE_US0,'F',1000000);
