The old Ericsson 4.8V technology bottom-of-the-phone connector.

Probably works for GA628 GH688 GF788 SH888

Looking down on the bottom of the phone, keypad facing away from you,
the connector should look like this:

	 | | [] | | | | | | | | | [] | .
	12 11  10 9 8 7 6 5 4 3 2    1

where "|" signifies a pin, "[]" is a hole and "." is a missing pin.

They appear to be numbered from right to left, skipping the missing pin.

Direction is relative to phone

pin	Direction
1	i/o	charger / accessory power
2	in	RS232 input (TTL)
3	-	digital GND		Raised pin *
4	out	RS232 output (TTL)
5	out	+5V output
6	in	Test (+5V=test mode)	
7	out	Mute (1=In Call)
8	in	Int/Ext headset		(open=internal, 0=external)
9	-	analog GND		Raised pin *
10	in	Accessory Sense		(connect to GND to enable external audio)
11	in	Audio
12	out	Audio

* Raised pin:  on the accessory connector, these pins are higher than the
others so that they electrically connect first.
