FMP, Winfax, and DDE commands

I've been playing around with using Winfax to send reports to fax machines using FMP 4.1. So far it works great if I want to send just one report at a time - click a button and BOOM - a report shows up in the customer's fax tray. What I'd like to do though is have this be more automated. When FMP launches Winfax, you have to interface with winfax manually before anything is actually sent (i.e. you must select a fax number, etc.) It seems that the only way around this is to have FMP send a DDE command to Winfax. Am I barking up the right tree here? Can I have FMP have Winfax send a report to fax machine without having to manually interface with Winfax. I've never done DDE stuff before and the DDE help in Winfax is very vague. If this is possible then can someone help me get the right DDE commands in place with the right syntax and everything? This would be a tremendous help. (Oh yes, and we'll probably be upgrading to 5.0 soon if that as any relevance.)
