J2534 Max and Min Packet Sizes

[Tazzi3]

As part of the J2534-2 compliance, there is an option to request a J2534 scantools maximum packet sizes along with alot of other tool specific information.

This should help resolve current and future tool support and dynamically set packet sizes.

Issue here, if the tool does not support J2534-2, so possibly have a defaulted smaller packet size? Thoughts?

I didn't know about this... Could you have the J2534Device class call use that method to set the MaxSendSize / MaxReceiveSize properties?

That way the serial devices would continue to work the way they do now, but the J2534 devices could make use of this.
