Is the computer a laptop or a desktop computer?

I ask because we have had trouble with 2 of the 4 laptops we have tried with Basic Stamps. I think the problem is with the output voltage of the serial port.

RS-232 has a wide voltage specification....initially spec'd with +/- 12v...but many laptops run a +/-5v signaling environment for the serial ports...and I think this might be the problem.

(but thn it is tough to debug things over email)

Good luck,
-Quentin
