Need a commport translation

Hi there,

I'mnot really into programming, but i work a lot with communication tools.
At this moment i need to link a communication program to an ISDN modem.
I managed to get my ISDN modem dialling using AT commands.
But my communication prog don't get te correct confirmations back from the ISDN card.

So i need a tool where i can set the reactions that are going back to the communication program, and depending on the commands- send strings to my ISDN modem.

Can someone help?

thnx

Something like this maybe?
