void sercom4Handler ( void )

Handles receive interrupt as it occur. Note:To use this interrupt handler you have to register it in usart_init() function as shown below. _sercom_set_handler(instance_index, sercom4Handler);

TMR_Status TMR_SR_SerialTransportNativeInit	(	TMR_SR_SerialTransport *	transport,
		TMR_SR_SerialPortNativeContext *	context,
		const char *	device
	)

Initialize a TMR_SR_SerialTransport structure with a given serial device.

Parameters:

transport	The TMR_SR_SerialTransport structure to initialize.
context	A TMR_SR_SerialPortNativeContext structure for the callbacks to use.
device	The path or name of the serial device (`/dev/ttyS0`, `COM1`)
