Ser2net is a software that can convert data between net and serial port.

opkg update 
opkg install ser2net

Use command ls /dev/tty*, and find the router’s serial port is called as ttyATH0.
Edit the /etc/ser2net.conf, find a line by searching for “2001” within this file and change it as following:

1
2001:raw:600:/dev/ttyATH0:115200 NONE 1STOPBIT 8DATABITS XONXOFF LOCAL -RTSCTS

Start ser2net server with command: ser2netConnect router’s uart to PC, and open serial port debugging assistant.
Open your command prompt or terminal, type telnet router_ip 2001. My router ip is 192.168.1.110, so I enter telnet 192.168.1.110 2001.

Now, test this server. I can type some characters in terminal, they are shown in serial port debugging assistant and vice versa.
