make sure you read all of Perry's notes, especially at the very beginning, of the Director movie script. It points you where to go for the Xtra you'll probably need as well as certain lines you will need to de-comment to run a check on the port.

also, i tried to cheat the system by connecting one keyspan adapter to the stamp, and another one to the serial communication cable. didn't work - my computer recognized them as separate entities and got confused. so use only ONE keyspan adapter, and have EITHER the stamp plugged in, or the serial communication cable.

Hmm -- actually, that should have worked, Kellee. Did you have them both plugged in before you started the Stamp software? Usually, the two adaptors will be assigned different but similar names (like USA19191.1 and USA191811.1), and you just have to make sure that you select the correct one for programming and communication.

You can figure out which is which by plugging one in first, running Keyspan Serial Assistant (in Applications) to see what its name is, then plugging in the other one & it should appear in the Keyspan window.
