GM862 EVK RS-232 Auto Power On

As subject line says, how do I power the unit on automatically? Did a few searches and couldn’t find anything specific. I see the ON/OFF pin on the edge connectors but there’s nothing in the EVK docs that says how to use it. I looked in the Telit hardware guide, but they talk of totem poles and pull-ups which is all Greek to me. I did read that applying 3.8v to the CHARGE pin might bring the unit up automatically (p19). Does that mean I can simply connect the 3.8V pin to the CHARGE pin on the breakout and be good to go?

I’ve also read elsewhere that the power button on the breakout can be tied to ground to get it to power on automatically. Is that a good simple way to do it?

I am not exactly proficient in electrical design, so any solutions needing pull-ups or totem poles or otherwise, might need to spelled out in “idiot’s guide” detail.

Does no one know how to do this? I would check the round solutions forum but I suspect the power up might be specific to Sparkfun EVK board.
