Hmmm, I've been using a Prolific for years with no issues. I don't know the model number of what I have. I actually believe it came with an old Speakercraft MZC system or learner many years ago.
Well i'm still stuck in the same spot with this new trendnet serial to usb. I am going to ask for a replacement MX850 cable that I bought off ebay. Maybe it was defective... I tried to do a continuity test but I don't even know if I am doing it right. The 3 wires will give readings from the db9 to the spots on the 3.5mm plug though.
