It seems that when a serial communication is received and printed in visual studio, the data is also sent back to the arduino through the serial port.

For example, let say all what my arduino does is receive a char and when this char is equal to 'A' it does "Serial.println("A");"

The expected result would only be "A" but actually, what I get is "A" being spammed in the visual micro monitor as if when the A is printed in the monitor it is also sent back to the arduino.

I tried changing the serial.println so it print B instead and this time the result is as expected (because of the if Serial.read() == 'A').

The only work around i've found is by starting the official arduino IDE and using its own monitor.

I have VS 2010 ultimate and the 1.0 arduino IDE version

If someone has a solution, I would appreciate

Works like a charm ! Don't know why I haven't thought of it earlier ^^

Thank alot
