Serial Port Sniffer ActiveX

Serial Port Sniffer ActiveX
Sniff and edit serial port data

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.

With Serial Port Sniffer ActiveX you can

 

Take full control of all signal lines

All signal lines (DTR, RTS, CTS, RTS) are supported. Moreover, the component's events include all of these lines state changes.

 

Sniff data flows between serial port and application

With Serial Port Sniffer ActiveX you will be able to fully monitor data flows between application and serial port. It gives you the possibility to detect control lines changes, handflow, baudrate and ring state changes, and track timeout updates. Serial Port Sniffer Components methods allow you to check whether the port is being sniffed, open the serial port to be sniffed and close the port after sniffing.

 

Take full control over the monitoring process

Serial Port Sniffer ActiveX gives you the ability to influence the monitoring process. As all transmitted data is intercepted in the virtual port, created by our component, you can easily substitute it with any data characters and commands of your own to get deeper into the monitoring process.

Àlvar Vaïllo Anglès, Spain

Simply Eltima’s Serial Port Sniffer is the most powerful solution I’ve ever tried to automatically mount a gateway between physical port and simulated port and take full control of it. Eltima’s ActiveX mounts easily a gateway between physical port and emulated serial port from an old software. I can now delete, replace, etc. information and it works really fine.

 

Carlos Alberto Fernandez, firmware development

We use Eltima Serial Port Sniffer ActiveX to intercept the data stream, single out the debug information and then redirect it to our Master application for further analysis. We simplified the process of debugging and testing our hardware with Serial Port Sniffer. Your product is excellent!

 

Yong-Ho Seo, CEO of XBOT Co., Ltd. from South Korea

We’re using Serial Port Sniffer ActiveX for building a monitoring and protocol conversion S/W for controlling and getting image of our toy robot to work with the educational graphical program. COM Port Sniffer saved us a lot of time on developing the solution on our own. And it satisfies our requirements perfectly.
