RS232 Data Logger by Eltima Software is an Open Source application which allows you to redirect all communication data from RS232 compliant serial port device into a text file for further analysis. RS232 Data Logger redirects data from any available serial port and works under Virtual Machine (VMWare). You can gather data from multiple serial ports simultaneously. RS232 Data Logger by Eltima lets you specify serial port connection parameters (baudrate, parity, stop bits, flow control, databits), select the file to redirect incoming data to for each port and append incoming data to already existing file. All data recorded as a text can be further analyzed. For instance, you can parse global positioning data (coordinates) from GPS device connected to your notebook via serial port to track your movement; or you can simply investigate and learn how serial ports work.
