If you're getting to the point of loading the software you're way ahead of us. We couldn't even see the serial port under Win2k8.
Can you see the COM port?
Perhaps they improved the drivers since 1.6.x...
Tim, i can't see the port inside W2K8 guest. It is conflicting with PCI Bus (afair). Also, i think that even if that would work (seeing the port), i would still fail to attach a debugger from the host, since Vbox seems to lock the port (if i start windbg attached to port, VM cannot start and vice versa).
EDIT: forgot to add that both VMware and Parallels Server have option to specify how COM port will behave. I.e. VM is COM server or client.
