Serial Port Monitor is a professional tool that every serial driver developer should have nearby. It's primarily used for monitoring and analyzing data traffic incoming or outgoing to a serial RS232 interface. The professional version allows you to tap into already opened ports in order to record and analyze the data passing through the opened stream, acting like a powerful serial Sniffer.
The program is able to show information categorized in several classes, dump-view, table-view, line-view and terminal-view. All the information recorded can later be exported to the format of your choice to be processed by any external application.
Virtual COM ports are also compatible with this software. It can monitor any number of ports simultaneously and provides a virtual-send mechanism in which you are able to send data to a device or application that uses a serial port.
The powerful built-in search and data filtering can be performed on the collected data to help you debug and locate protocol or interface errors quickly, making the job of a serial protocol analyzer / debugger a sweet and amazing experience.
