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 (doesn't matter whether it is virtual or real one) and works under Virtual Machine (VMWare). You can gather data from multiple serial ports simultaneously. All data recorded as a text can be further analyzed. For instance, you may parse global positioning data (coordinates) from GPS device connected to your notebook via serial port to track your movement; or you may simply investigate and learn how serial ports work. RS232 Data Logger is able to select the file where to redirect incoming data for each port and specify serial port connection parameters (baudrate, parity, stop bits, flow control, databits). Among other hot features of this Data Logger is real-time counter of the received and stored bytes and the ability to work under Virtual Machines. The utility allows you to disable/enable logging on-the-fly and append incoming data to already existing file. RS232 Data Logger is provided with source code (MFC/C++ VC7.1).
