title: Logging data received to a txt file
body: <p>I want to log data to a txt file, i.e. I will receive the data from the com port and then write it to the text file. Does this qualify as logging? or is logging referring to error logging? If the first case is true I guess I am supposed to use log4j as I have read that this is the standard for logging? However if this is not the case is it then ok to use FileWriter? </p>
