## Serial control
|
||||||
|
|
||||||
|
If you open a serial terminal to the ESP you will see a summary of all variables which reflects CAN messages sent to the Easylink.
|
||||||
|
You can modify these with just typing in.
|
||||||
|
|
||||||
|
For example if you want to start the system, type:
|
||||||
|
|
||||||
|
```
|
||||||
|
iginition on
|
||||||
|
````
|
||||||
|
|
||||||
|
All CAN frames are now sent.
|
||||||
|
|
||||||
|
You can set brightness mode to day or night for example type
|
||||||
|
|
||||||
|
```
|
||||||
|
brightness night
|
||||||
|
```
|
||||||
|
|
||||||
|
If you need a new summary of all new states, just hit RETURN without any command.
