s2e (Serial to Ethernet)
The s2e program demonstrates serial to Ethernet tunneling and a configuration web interface.
Note that the boa web server must be enabled with ‘make menuconfig’ in order to take advantage
of the web interface.
To access the s2e settings when the s2e and boa processes are running, use your web browser
to connect to: http://<target_ip>/

If the tunnel is configured for server mode, you can now telnet to the target’s IP address at the
configured TCP port number to access the serial port.
telnet <target_ip> <tcp_port_for_tunnel>
