If you intend to access the router through serial console all that you
need is explained here:

Hi again
I downgrade to Attitude Adjustment and know i have setserial and stty.
How can i use this /dev/ttyATH0 as a serial port for send/receive
information and not as a port for access from outside?
Let me explain.
I have a door with one of this
http://es.ideas4all.com/ideas/0000/0447/iman.jpg
When the door is open i have this contact open and the information send
through /dev/ttyUSB0 never come back. Whe the door is closed the
contact get closed and when you send something through /dev/ttyUSB0 the
same come back again.
echo "0" > /dev/ttyUSB0 (send information)
head -n 1 /dev/ttyUSB0 (try to receive something)
I create a loop for those commands and send & receive every second and
it's working OK when i use USB to RS232 (manhattan tl2303).
Now i want to use tl-wr740n because this hardware is cheap!
When i do the same using /dev/ttyATH0 (the tty from => dmesg | grep tty
) i can't see the information comming back.
I use the the J1 pins 1&2 on the picture [1] in the bottom right.
TX is the pin1. the one with the drawing around
RX is the pin2.
I think i have a conflict with serial because this for connect from
outside the router. I edit /etc/inittab and delete information about
/dev/ATH0 and then reboot but i have the same symptoms.
Thanks for your time.
Emiliano.
