Help me please

Hello, I am using a program (onchannel) to receive keys from a server. This program forward the keys to any com port I desire. I would like to use this onchannel program with my DVB Dream pc software. Can anyone suggest me what plugin I can use so I will force the DVB Dream program to connect to a specific com port so it can read those keys ?

Thanks in advance for your time and I apologie for my poor English
