Product details

Serial Port Sniffer ActiveX Control is a powerful and feature-rich ActiveX component, that is able not only fully monitor serial ports, but also edit data flows.

Its logic is very simple: our component creates additional virtual COM port in the system with the same name as the monitored serial port. All data flows go through created virtual COM port and are logged into a special document. Meanwhile, you can easily substitute any chunks of data with your own to influence the process of serial port communication the way you need.
