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.

Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplUserNContributed)Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines(3pm)

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines - Use concatenation or HEREDOCs instead of literal line breaks in
       strings.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Strings with embedded line breaks are hard to read.  Use concatenation or HEREDOCs instead.

	   my $foo = "Line one is quite long
	   Line two";					 # Bad

	   my $foo = "Line one is quite long
Line two"; # Better, but still hard to read

	   my $foo = "Line one is quite long
"
	       . "Line two";				   # Better still

	   my $foo = <<'EOF';				 # Use heredoc for longer passages
	   Line one is quite long
	   Line two
	   Line three breaks the camel's back
	   EOF

CONFIGURATION

       This Policy is not configurable except for the standard options.
