Records all data received on a serial port to a file on a disk. It was originally designed to record telephone traffic data from a corporate phone system (PBX) for later analysis. For this reason, it was designed to be very robust and includes features to notify an administrator if no data is received in a certain amount of time. However, it is generic enough to be useful whenever one-way serial traffic needs to be recorded. Unlike most other serial logging applications, Serial Logger Service runs as a service so that it starts as soon as the operating system starts and doesn't require a user to log in and run it.
