Abstract definition of UDS packet type.

Packet type information is carried by Network Protocol Control Information (N_PCI). Enums with packet types (N_PCI) values for certain buses (e.g. CAN, LIN, FlexRay) must inherit after this class.

Note

There are differences in values for each bus (e.g. LIN does not use Flow Control).

Initialize self. See help(type(self)) for accurate signature.
