How to enable/disable Android logcat when using a custom kernel

Android, How to, , , , ,
A good source of information could be found in this page, but none of them worked for me.

The most useful article I found was on xda and here’s the solution:

  • enable 
    echo 0 > /sys/module/logger/parameters/log_mode
  • enable at boot, but not when suspended 
    echo 1 > /sys/module/logger/parameters/log_mode
  • completely disabled: 
    echo 2 > /sys/module/logger/parameters/log_mode

(you need a rooted device)
