Hello.
I use an older PC for some automation tasks with a relay board like this: link.
This basically works well, but I have a problem. When I shut down the PC but leave the monitor switched on, the relay also stays switched on. If I turn off the monitor, the relay will turn off.
The problem is that the LPT port should turn off with the PC regardless the energy state of the monitor. That works on my other computers.
The motherboard is an ASUS P5LD2-VM, the monitor is a CRT.
