First of all, the cable is for the parallel (printer) port, and not RS232
(but perhaps that's what you meant?)... Second, the cable is a "hack" and
has nothing to do with TI's official linkcable (Graphlink) so I don't
think Texas can (or even want) help you.
As to getting the cable to work; Make sure your parallel port works OK first,
than try the "linktest" program to see if the cable is OK. We made the
cable exactly as it said in the description and it worked the first time.
