like Stefan said, I have used the seconde method using  the Fiasco.OC specific UART driver under 'os/src/drivers/uart/kdb'.
I added this to my run script:
<start name="uart_drv">
		<binary name="kdb_uart_drv"/>
			<resource name="RAM" quantum="1M"/>
			<provides>
				<service name="Uart"/>
				<service name="Terminal"/>
			</provides>
			<config>
				<policy label="terminal_mux" uart="1" detect_size="yes"/>
				<policy label="noux" uart="1" detect_size="yes"/>
			</config>
			<route> <any-service> <parent/> </any-service> </route>
		</start>
then, I can use console line on seria line.
However, there are some problem in my console line. You can see the problem pictures in attachment.
One is that When I enter one character, it will write this character twice. For example,
if I enter one 'a' in the console line, it will appear 'aa' in the screen. but the fiasco kernel get the right one 'a'. 
The other problem is that when i enter another path using the command 'cd ', the path can not appear int the front of console line. You can not know what path you are.
thanks.
