hi i was wondering if i could use my decks remote wire (the one that tells my amps to turn on and off wen the deck does) to turn on and off my pc. i am planning to plug it into the com port and set it up like Nicorolla did in his post carPC Turn On / Shutdown Controller by conecting the remote wire to pin 8 on com 1. and setting up a generic ups to have it go into hibernate or to shutdown wen the deck does.
(the green line is the remote wire going to the com port)

(These are the ups settings that are from nicorolla's post. i think they should work the same right?)
Thank you so much.
