I installed grbl v0.9, and when I access the serial port from Tools/Serial Monitor, in arduino app , or the app "Universal Gcode Sender", the arduino returns me:
Grbl 0.9j [ '$' for help]
[ '$ H' | '$ X' to unlock]
Perfect. This is how it has to work.
I made a program in c++ to handle the serial port. If I close the port and I open them again, the arduino is not reset and not the blocking message appears.

¿Someone knows why can it be?
