How can I create a serial port sniffer?

Last Modified: 2013-11-26

I need to be able to sniff a com port so that I can create a trigger when another piece of software communicates with the device on Com1.

I've found an activex control called Serial Port Sniffer by a company called Eltima Software, but that fails to work and i can't get them to give me support over the phone.

Any ideas of how i can do this? Or anyone know another control i can purchase to do this that isnt Eltima?

Many thanks
