[SOLVED] Does the arduino reset when you open up serial monitor?

Development Tools IDE 1.x

For a while now I thought the arduino reset when you open the serial monitor. Now I'm not sure.

When I run this simple program:

void setup() {
  Serial.begin(57600);
  Serial.println("Setup");
}

void loop()
{
Serial.println("Loop");
delay(1000);

}

and open the serial monitor I see the loops being printed, but not the Setup being printed. I have to press the reset button to see the setup printing.

Is it supposed to be like this?

I'm sure ages ago if I closed and reopened the serial monitor the program would reset and I would then see the setup being printed.

Mine does (1.0.5, FTDI equipped arduino).

At that speed I get garbage, but at 9600 it prints setup-loop-loop etc and I tried it a few times, each time it prints setup-loop-loop

Uno and 1.0.5

Now I'm confused - why doesnt mind :frowning:

Arduino Uno.
v1.05
Running Windows 8

Update: Also tried dropping baud to 9600 - didn't fix it.

Update: Ahh - problem fixed. I tried 1.0.1 and it works as it should. Tried my version - broken. Downloaded a new 1.0.5 and it works.

After examining some files and racking my brain it turns out a while back I installed a new rxtxSerial.dll file which fixed slow serial problems as per here http://forum.arduino.cc/index.php/topic,46977.0.html

I think this was fixed in 1.0.5 so no need for the new file.

I recopied the file from the fresh download and it fixed the problem.
