Randy, I had the same issue. I have an older NI GPIB to serial adapter, and since the Tektronix protocol was so customized - I couldn't get it to recover the data either.
Right now I'm experimenting with a different PC serial program - which is designed to transfer data from embedded systems like Arduino. I would like to capture the data including the control characters without having to convert them. This effort is helping me get a deeper understanding of what is going on, so I can get my GPIB flash drive designed properly.
