Getting free of the Arduino IDE serial monitor, this python code works.

First, on the mac, import pyserial:

Code:
sudo pip install pyserial

Code:
macos# cat ard.py

The code:

Code:
import serial

ser = serial.Serial(
    port='/dev/cu.usbserial-40',
    baudrate=9600,
    parity=serial.PARITY_NONE,
    stopbits=serial.STOPBITS_ONE,
    bytesize=serial.EIGHTBITS,
    timeout=0)

print("connected to: " + ser.portstr)

# this will store the line
line = []

while True:
    for c in ser.read():
        line.append(c)
        if c == '\n':
            print("Line: " + ''.join(line))
            line = []
            break

ser.close()

Run it:

Code:
python ard.py

Output from Arduino on my mac using python to read it:

Code:
macos$ python ard.py
connected to: /dev/cu.usbserial-40

Well, this is a bit too easy..... we all can easily set up all kind of sensors in our homes, in our motorcycles or cars, and push the results to a DB on the net and display the results on the web.... even on this site. Or M2M....

Hmmm.

Geometry::Primitive::Line(3pm)				User Contributed Perl Documentation			    Geometry::Primitive::Line(3pm)

NAME

       Geometry::Primitive::Line - A Line

DESCRIPTION

       Geometry::Primitive::Line represents a straight curve defined by two points.

SYNOPSIS

	 use Geometry::Primitive::Line;

	 my $line = Geometry::Primitive::Line->new();
	 $line->start($point1);
	 $line->end($point2);

ATTRIBUTES

   end
       Set/Get the end point of the line.

   start
       Set/Get the start point of the line.

METHODS

   new
       Creates a new Geometry::Primitive::Line

   contains_point
       Returns true if the supplied point is 'on' the line.  Accepts either a point object or an x y pair.

   grow
       Does nothing, as I'm not sure how.  Patches or hints welcome.

   is_parallel ($other_line)
       Returns true if the supplied line is parallel to this one.

   is_perpendicular ($other_line)
       Returns true if the supplied line is perpendicular to this one.

   length
       Get the length of the line.

   point_end
       Get the end point.  Provided for Shape role.

   point_start
       Get the start point.  Provided for Shape role.

   scale
       Does nothing at the moment.

   slope
       Get the slope of the line.

   to_string
       Guess!

   y_intercept
       Returns the Y intercept of this line.
