Re: [opendiag] OBD-II Intialization

Shane,

You'll have to send 0x33 just once and then listen for a reply at 10400
baud.
Iff you take a look at what VagCom sends it will be 0x33, try to connect for
four times.
I see you do have the HS3000 book. I thought it will all be in there??
Maybe you can pass me some off these specs so i can have a look at it.
Till now I think its initialisation at 5 baud whit the messages for:
ISO 14230-4 0x33
ISO 9141-2 0x6A
I didn't try these so it could be wrong.
