Hi Keith,

I have never seen this problem, but I don't use Vista... Do you know what IC chip is 
used in the adapter? Updating the driver from the manufacture may fix the problem. I 
have found that USB-to-RS232 adapters based on one of the FTDI chips 
(http://www.ftdichip.com/) work the best. If you can't get it to work right I would 
place a PCI or PCI-E RS232 Comm Port board into the computer. They can be purchased 
on eBay for under $20.00. Just make sure they have Vista drivers for the board.

Regards,
Larry Cochrane
