I have used a Radio Shack USB to Serial port cable. It uses some electronics and software to assist in the conversion process. Works perfectly:

I have that exact cable, and cannot get it to work. I connected it to the virtual machine, ran the installer, but each time I plug it in or reboot the machine, it's considered new hardware and the new hardware wizard pops up. Computer Management -> Devices -> Ports shows the USB Serial Controller, but it's got the ! icon. Diabling/Reenabling the device does not help. Having a serial port defined in the VM settings makes no difference.

It's running hideously slowly driving my PIC programmer -- so much so that limping is a better description -- but it is running.

You put in the CD, and then insert the device. Windows Installer Wizard will come up and when you ask it to look for the driver, it won't find it. Banish the Wizard, then open the CD and run the installer program on it. It will run but there will still be complaints and it won't work. Now unplug and replug the Radio Shack USB cable. Up comes the Wizard again, but this time, it'll be able to find the driver. Use it to install, and you're in business. COM3 comes alive. It's horribly slow on the real PC too, but Parallels is a fair bit slower still.

I'm trying a generic PL-2303 USB-serial cable -- noticed a couple things: * Before I installed the Mac OS X driver, Win2K thought it was happy using it, but serial receive didn't work, so no dice. * Then I tried the Mac OS X driver from SourceForge (linked from Apple's own pages). This worked great for OS X, but now Parallels can't get hold of it for Windows, so can't even try to get it going from Windows anymore. Fred

Now if someone could tell me a trick to get it to work with my Apple USB modem so I could use it to dial from a Door Security app in Windows I'd be set!
