Parallel port data output
Hello,
I build relay switch for parallel port and it works with Z-ParSwitch as I hope to.
Problem is if PC shuts down then relays get power for moment then turns off
Win7/32 boot and all data pins D0...D7 switch on
Even after deinstall Z-ParSwitch thats happen.
Is in WIN7 Ultimate possibility not give 5v to parallel port data pin D0...D7 when booting up?
Please help
