Looks like only Mindsensor provides port splitter for nxt motors. Unfortunately, this splitter will not allow independent control.

You'll need to either get the RCX 2.0 software or use NQC. As far as I know no one has (yet) managed to use the IrDa port and I believe Vista doesn't support Serial ports... you might try a USB to Serial converter, but that doesn't always work. (...) (17 years ago, 3-Mar-08, to lugnet.robotics)
