Serial monitor hanging the IDE on OS X

Hi,

I'm trying to get some serial data back from the board. When I run the analogInSerial example and switch on the serial monitor, some numbers appear initially but then the whole IDE gets really unresponsive, and I need to 'force quit' it. I'm using a Rev3 board with MapleIDE v0.0.12 on Mac OSX 10.6.8. Does anyone know how to fix this?

thanks,

Chris

Are you using a Hardware UART for serial or the USB serial?

Try using a standalone serial terminal like CoolTerm, as I find it to work better than the Arduino IDE's one.

luma, interesting. Could definitely be a bug in serialusb but its almost certainly to be threading issue with the serial monitor in the IDE+Mac+your java install cropping up that example writes to the serial port so fast (probably something like 10000 samples a second). If you can afford to, slowing things down will almost certainly fix the problem.
```
void loop() {
    int val = analogRead(in);
    SerialUSB.println(val);

    delay(10) // should give samples at 100Hz
}
```
If you cant afford to lose the speed, try a different serial monitor as suggested.
