{
	unsigned char cval = UART_LCR_WLEN8;
	unsigned int quot = AVR_QUOT(avr_clock);

	cval |= UART_LCR_STOP | UART_LCR_PARITY | UART_LCR_EPAR;

	out_8(avr_addr + UART_LCR, cval);			/* Set character format */

	out_8(avr_addr + UART_LCR, cval | UART_LCR_DLAB);	/* set DLAB */
	out_8(avr_addr + UART_DLL, quot & 0xff);		/* LS of divisor */
	out_8(avr_addr + UART_DLM, quot >> 8);			/* MS of divisor */
	out_8(avr_addr + UART_LCR, cval);			/* reset DLAB */
