Reasonably priced USB to serial adapter
Mandolin Guy
For those needing a USB-to-serial adapter, Cyberguys has one that's reasonably priced. See IOGEAR USB to Serial/PDA Converter Cable GUC232A - Cyberguys.com

The ad says it doesn't work with Vista or Windows 7 but it gives information on how to get the drivers for those systems.

I'm not endorsing the items. I don't need it and have never tried it. This is for information only.
