Namespaces
namespace	BridgeSerial
	Controller-side serial link used to exchange payloads with lsh-bridge.

Functions
void	BridgeSerial::init ()
	Initialize the serial port used to talk with lsh-bridge.
auto	BridgeSerial::receiveAndDispatch (uint16_t maxBytesToConsume) -> ReceiveResult
	Consume a bounded amount of serial input and dispatch at most one payload.
void	BridgeSerial::tickSendIdleTimer (uint16_t elapsed_ms)
	Advance the ping idle timer used by canPing().
auto	BridgeSerial::canPing () -> bool
	Check whether the bridge link may emit another heartbeat.
void	BridgeSerial::updateLastSentTime ()
	Record that a payload has just been transmitted to the bridge.
auto	BridgeSerial::isConnected () -> bool
	Check whether the bridge is still considered connected.

Variables
uint16_t	BridgeSerial::sendIdleAge_ms = UINT16_MAX
	Elapsed idle time since the last payload was sent, saturated at 65535 ms.
uint16_t	BridgeSerial::receiveIdleAge_ms = UINT16_MAX
	Elapsed idle time since the last valid payload was received, saturated at 65535 ms.
