I have some devices (solid state relays controlling large mains power supplies) running off the true serial ports on my motherboard. I use this set up to remotely switch the supplies on or off via remote desktop using a simple DOS program. However, on boot up Windows 7 64 bit seems to "poll" the ports sending outputs momentarily high a few times. The SSD's, the big linear power supplies and I don't like this! Can it be stopped? Thanks.
