Multiple PICs on usart network

OBD-II signal protocols. ISO 9141-2. This protocol has an asynchronous serial data rate of 10.4 kbit/s. It is somewhat similar to RS-232; however, the signal levels are different, and communications happen on a single, bidirectional line without additional handshake signals.

I'm planning on using standard 2-wire hardware USART.

Car automakers had to do it with better electrical characteristics I guess.

I'd also choose 2 wires USART classic setup. Tested and guarrateed to work just fine.
