Took a little digging but I found the thread where you were talking about port 20/21. I was able to configure the 3P+S card and run the test from the solivant site successfully, but I'm not able to upload basic. I have a couple more things to try, including setting a small upload delay as Bill suggests on his page. http://www.vintagecomputer.net/browse_thread.cfm?id=318 However, I'm thinking that I may still have a configuration issue on the 3P+S card. But I think I'm getting close.
