Checked the motherboard last time I was out there - no 'on restore power' though... pic + relay I think. The power control over the phone line was done using a commercial unit - a Technotrend TPS2000 which will answer the line and switch on/off a built-in power socket according to received DTMF commands. ----- Original Message ----- From: "Herbert Graf" To: Sent: Wednesday, June 19, 2002 6:16 PM Subject: Re: [EE]: Cycling power remotely on an ATX PC > Most motherboards have a "On restore power" setting, if you set that to > "power on" it will power up after a power failure (which is what you are > doing).
