I've searched on and off for a couple of days, and cannot find a thread at Parallels or here that specifically addresses my problem or provides a workaround. With some of the work that I do, I have to use an analogue serial modem to dial directly into servers in cases where they have lost contact with the outside world. There's no way around this...don't bother speculating or assuming...just assume this one thing: I have to dial directly into analogue modem banks in cases where individual machines have lost contact with the outside world. I am on the iMac referenced in my signature. I have a USB modem connected that is recognised by OSX and recognised by Windows 7 64-bit Ultimate in the Bootcamp partition. The terminal application and the modem work just fine when I start the machine in Bootcamp and run everything through Windows. However, I cannot seem to get this to work in the virtual machine through Parallels. There isn't any relevant answer from Parallels or Apple support forums, and searching here doesn't reveal anything, either. The modem just won't get recognised in Windows running in a virtual machine. Any ideas, folks? It's not an emergency. This is only going to happen very rarely, if ever, and I only have to test it once/week, and for this I can certainly boot into the Windows partition to do it. But you'd think that with all these cores and all this technology and stuff, there'd be some way to do this in the Parallels virtual machine.
