Is it possible for a computer to send data to an Arduino connected as a serial device via the windows command line? i.e: Is there a command line function that can send data retreived via the command line directly to the Arduino. So for example I could run "tasklist" and have it send the results straight to my Arduino for future parsing.

So, exactly how the info is saved and parsed will partly depend on the method used to retrieve the data. I guess the important question here is: is it possible?
