Note:

• The Virtual Serial Port Setup option is disabled on 64-bit Windows platforms (including Windows 7). Also, they do not work on Windows 8. To add serial ports to 64-bit Windows, use a usb-to-serial converter. Alternately, you can use a third-party virtual serial port program.
• If you have not run Virtual Port Setup before, it will be installed when you try to run it. You will then be prompted to reboot the computer.
• The first time you set up and try to use virtual serial ports after installing them and rebooting the computer, you may see an Error: COMx.Read (), code 87 message in the Virtual Port Setup window. If this occurs, reboot your computer again -- the virtual serial ports should work fine after this second reboot.
• If you get a Could not find OEM file error after your computer reboots, copy the file "vsp.oem" from the folder where CIUMon is installed to the system32 subfolder of your computer's Windows folder.
• If you later install more physical serial ports, you should delete all of the virtual serial ports and connections first, then re-create them after the new physical ports are installed and working.
