          its how to connect 2 telephones for a intercom without using any phone lines.

          Down further it explains how to make the phone ring which is what u need

          only problem is it needs alot of volts and the way to ringing works is a certain frequency so if i made that it would wake the pc up

            40-90V seems like way to much for those small wires. Any other suggestions??

              You have a built-in modem, it's not quite as easy as having a com port to play with! One solution is to solder wires onto the on/off switch inside the laptop or docking station. (a docking station may give you a com port)

                but im having a problem trying to find the pin outs for the switch under the lid to soldier my own switch to. any idea?? it is a 4 pin switch and i have measured the voltages when the switch is depressed and no voltages showed up higher than a clear 0V???

                  It's probably just shorting two pins together, rather than creating voltage. Put your multimeter into "Circuit" mode and make it beeeep

                      This is the voltage of phone line though. I have multimetered a phone jack before and its something like 50V at a dialtone and supposedly double that at a ring. Not very high amperage obviously.. the hard part may be trying to generate that kind of voltage in the car ouch.
