 # Command Line Interface
 Advanced configuration has to be done via the command line on the console interface. This console is available either via the serial port at 115200 baud or via tcp port 7777 (e.g. "telnet 192.168.4.1 7777" from a connected STA).

 With "set status_led GPIOno" the GPIO pin can be changed (any value > 16, e.g. "set status_led 255" will disable the status LED completely). When configured to GPIO1, it works with the buildin blue LED on the ESP-01 boards. However, as GPIO1 ist also the UART-TX-pin this means, that the serial console is not working. Configuration is then limited to network access.
 
+# HW reset
+If you pull low GPIO 0 for more than 2 seconds, the repeater will do a factory reset and restarts with default config.

 # Port Mapping
 In order to allow clients from the external network to connect to server port on the internal network, ports have to be mapped. An external port is mapped to an internal port of a specific internal IP address. Use the "portmap add" command for that. Port mappings can be listed with the "show" command and are saved with the current config.
