Serial monitor behaves differently on Windows vs Mac

Sorry, I had to drive up to Minneapolis for two days and just returned.  I've posted the code below, but I don't know if that will help.  I'm using the exact same code on the Mac machine as on the Windows, and it compiles fine on both.  I'll also post a screen shot of the Mac Serial Monitor and the Windows Serial Monitor so you can see the difference.   Unfortunately I won't be on the windows machine until Thursday.  Standby for the screen shots.

/*

Potentiometer SKETCH

Read level between 5V and Gnd as set by a potentiometer

*/

const int sensorPin = 0;   //select input pin for pot level

const int ledPin = 13;     //select output pin for LED

int potlevel = 0;        //variable to store value of light level

void setup()

{

  Serial.begin(9600);      //send and receive at 9600 baud

  pinMode(ledPin, OUTPUT);  //declare the ledPin as an output

}

void loop() {

  potlevel = analogRead(sensorPin);  //read voltage on the photosensor pin

  potlevel = map(potlevel, 0, 1023, 0, 255);

  digitalWrite(ledPin, HIGH);          //turn LED on

  delay(100);                   //hold LED on

  digitalWrite(ledPin, LOW);

  delay(100);                  //LED is off for same period as it is on

  Serial.write(potlevel);      // write potlevel to serial output as a byte

}

As to 'credit where credit is due,' I usually do use the CA/HA feature, I just haven't been at my computer in the past couple of days.  Once I get a chance to go over and check out the answers, I'll be sure to give credit.

Thanks,

Somehow this solved itself.  I went back to using Serial.println() as Billabot suggested and I am getting the correct values displayed on the Serial Monitor.  Obviously a mental lapse on my part.  Hmmm.

I do have another question, however.  I like to use the Serial Monitor for debug and to monitor data in the sketch.  Each time I upload a sketch due to making corrections or whatever, the Serial Monitor goes away.  I then have to type Shift-Cmd-M to restore it.  Is there any way to keep the Serial Monitor screen from going away each time a sketch is uploaded?

Thanks again,

Kevin H.

I cannot find an answer to your question.  So, what to do?   .... mmmm.....  I think I will  ....  tweet someone who can help us.
