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.

NAME

       cyclades-serial-client Serial Port Interface for Cyclades Terminal Servers

SYNOPSIS

       cyclades-serial-client (start | stop | restart | status) [devname]

DESCRIPTION

       For  each  physical  port listed in cyclades-devices file, cyclades-serial-client controls the status of the corresponding cyclades-ser-cli
       interface.

OPTIONS

       cyclades-serial-client must be invoked with one of the (start, stop, restart or status), and optionaly with a argument associated to a spe-
       cific device.  In this case, the action spedified as the option will be performed only for this device.

       If this argument was not supplied, the action will be performed for all devices listed in cyclades-devices file. The mandatory options are:

       start  -  Starts the cyclades-ser-cli program, using parameters supplied in the cyclades-devices  file. If this program is already running,
	      a message will be displayed, and no additional copy will be started.

       stop   - Stops the cyclades-ser-cli program(s), by issuing a SIGTERM signal.

       restart
	      - Simulates a hangup to cyclades-ser-cli program(s), by issuing a SIGUSR1 signal.

       status - Checks the status of cyclades-ser-cli programs(s).

EXAMPLES

       Assuming the the following cyclades-devices file configuration:

       /dev/ctty01:pr3k:1:rtelnet: /dev/ctty02:pr3k:2:socket:

       1 . Start all devices: cyclades-serial-client start Messages: "Starting /dev/ctty01  <==>  pr3k:1  interface"  "Starting  /dev/ctty02  <==>
       pr3k:2 interface"

       2 . Try to start them again: cyclades-serial-client start Messages: "cyclades-serial-client : /dev/ctty01 already active" "cyclades-serial-
       client : /dev/ctty02 already active"

       3 . Stop only /dev/ctty01 device: cyclades-serial-client stop /dev/ctty01 Messages: "Stopping /dev/ctty01 <==> pr3k:2 interface"

       4 . Checking status: cyclades-serial-client status Messages: "/dev/ctty01 (rtelnet at pr3k:1) is inactive" "/dev/ctty02 ( socket at pr3k:2)
       active, pid 2983"

       5  .  Start  a  non-valid  device  cyclades-serial-client start /dev/xtty01 Messages: "cyclades-serial-client : device /dev/xtty01 does not
       exist"
