COM Port Sniffer ActiveX

Serial Port Sniffer ActiveX Control is a versatile component that you can embed into your application to enable it to sniff (monitor) serial ports in the system, meaning that it lets you track all serial port activity and learn which applications are using the particular serial port. Besides, Serial Port Sniffer ActiveX Control enables your application to edit any data going to and from the serial ports being monitored.

Sniff data flows between serial ports and applications

Serial Port Sniffer ActiveX enables your application to monitor all data flows between applications and serial ports, to detect changes in the state of control lines and hardware flow lines, baud rate, and ring state, and to track timeout updates. Methods supported by the component allow you to check whether the port is being sniffed, to open the serial port for sniffing and to close the port when the sniffing session is over.
