We have a software application that we have been running on Windows XP on a Panasonic Toughbook. The app controls a device which is connected to the Serial db9 port. The software sets the port settings per its need. Now we have another Toughbook that runs Windows 7 64-bit. On it we have installed Microsoft's XP Virtual Machine. The app runs happily in this VM. But the app cannot find the COM port. In the user settings for the VM we are given the option of connecting to a USB port. Is there something like that available for connecting to COM ports? Or how can we let our app see and use a COM port?
