I have a ADSL2+ modem&router .
I tried to install openwrt on it . I tried to connect to that via serial port .
GND ---- GND
TX ---- RX
RX ---- TX
with 115200 , 8, 1 ,none
I tried some software like putty , realterm ,...
but have any chance to connect to that .
also I tried others baudrate like 9600 ,.... , 115200
Do I need some special cable ?
or I missing some thing ?
, .... ?
Thanks
