Yes, you are right.I have finished it. but i find a bug that it seems to be in "static int alt_avalon_uart_tiocmset (alt_avalon_uart_dev* dev, struct termios* term) " function

of the altera_avalon_uart.c .

IOWR_ALTERA_AVALON_UART_DIVISOR(dev->base, ((dev->freq/speed) - 1)); the speed should be

thank you for reply!
