I've got a Super Serial Card, and I'm having trouble with it. I went on the ADTPro website, set the jumper block to down(straight through cable).

Then I set the DIP switches to as shown in the photo on their site. 1001111 1101100.

According to wikipedia -

The source code for this was released after his passing.
