AIU is set default not enable.
I solve the problem but further testing will go on. The Belkin Serial to USB that I have been using for serval years does not like Window's 10. I switch out the cable for the serial to usb cable that came with my ESU programmer and things are working fine now. Was able to monitor the cabs, backup, add marcos. set clock etc. So I guess I have to buy the Keyspan Serial to usb now. Thanks for all the help.
