Hello to all. I am new to hacking routers. Recently I have been trying to connect wr740N to pic18f2550 via serial console of wr740N. I have identified a 4 pin connector in which one pin is vcc, one is ground. My guess is that other two pins would be tx and rx. I have tried to connect it pic to see if any data is comming during boot process but failed. Can anybody guide me in the right direction that whether I am using the right pins from wr740n pcb or not.
Thanks.
