I understand Jerry and I agree that if there is no other way to achieve error-free transmission and reception, your approach is the right one. OTOH, I can see no reason that the problem cannot be solved in the digital domain. As far as I know, there is no basic science or engineering that demands the intermediate conversion to the analog domain to solve this problem properly, hence my desire to attack this problem in the digital domain to see if I can solve it there. FWIW, my current hypothesis is that there is some high-priority process that is part of Windows that is causing a problem. My next attack on the problem will be to remove all unnecessary tasks from the standard out-of-the-box Windows XP task mix. For example, things like automatic software updates, NETBIOS, SMB file sharing, etc., are not necessary and consume resources unnecessarily. I am going to turn all those "features" off to see what the impact is on performance. I will post the results of my experiment. While my background is in software development and while I do have a lot of experience with real-time, event-driven OS's doing communications software (I used to design routers), I have no experience with making Windows work properly so I am shooting in the dark here. I invite anyone with experience in this area to advise me.
