Slsnif is a serial line sniffer software. It listens to the specified serial port and writes all data coming through it into either stdout (default) or a log file (if specified -- see option -l ). Slsnif operates either by creating a pseudo tty (pty) and linking it to the serial port, or by linking two serial ports together.

Installation and proper configuration of the Device Monitor service is a stumbling point for many users. Please follow these KB (knowledge base) articles for more information:
