serial monitor of Arduino programer.

When I start the "serial monitor" of arduino programer, the "L" led in the Arduino board blink.

some body know the ASCII secuence that the "serial monitor" send?

Thanks.

Opening the Serial Monitor resets the Arduino. There is no actual communication between the Serial Monitor and the Arduino until you press the Send button, after typing something in the text field.

But i'm tring to make the same from a C sharp program. How could I reset the arduino sending a rs232 comand?

Opening the serial port in the C# application also resets the Arduino. You don’t have to do anything.

I don´t know what hapend, but when I open the port from c sharp, Arduino dead or is bloked.

But if I press the Reset button in the Arduino board, the Open form csharp work well.
