1. An apparatus comprising:
a node connection comprising two select line connections for a select line of a serial network, wherein the serial network is a Local Interconnect Network (LIN) and the select line is discontinuous at the node connection;
a bus direction module that listens at the two select line connections for a selection signal, wherein the selection signal is a LIN selection signal, and in response to detecting a selection event of receiving the selection signal at a first select line connection, the bus direction module configures the first select line connection for a LIN input select line and a second select line connection for a LIN output select line, and outputs the selection signal on the second select line connection to a second node connection;
wherein at least a portion of the bus direction module comprises one or more of hardware and executable code, the executable code stored on a memory.
