Well, here's the little I can offer. My desktop supposedly supports this
feature. Here are some of the caveats requirements. Note, I'm taking
this from my motherboard specs (Intel SE440BX), so some items may vary.
* You must have a motherboard that supports "Wake on Ring"
* You must have a BIOS that supports Advanced Power Management
* You must have an ATX-compliant power supply that supports remote
power-on/off.
* You must have a modem configured on COM1 (ttyS0) - BIOS configured
presumably.
* APM must be enabled in the BIOS
* You must have an operating system that supports APM and can request
soft-power off - as opposed to normal hard power off.
If properly set-up. The first call will wake the system, while a
second call will be required to actually make a connection.
My experience with full-blown APM with Linux on my desktop led to some
mostly minor, but annoying problems. So, I only have it set-up to do
power-off. However, I assume laptop user's do this all the time, so I
may have had something incorrectly configured. I don't really have a
need for this feature, so I haven't investigated it further.
I suggest you get some documentation on your motherboard and power
supply. That's the only way you'll know if the system may be able to
do this.
