function out=RPI_serialOpen(device,baud)
// Function to initialize a serial device
//
// Calling Sequence
// RPI_serialOpen(device,baud)
//
// Parameters
// device: device to connect to
// baud : the baud rate for communication
//
// Description
// This function opens and initialises the serial device and sets the baud rate. It sets the port into “raw” mode (character at a time and no translations), and sets the read timeout to 10 seconds. The return value is the file descriptor or -1 for any error, in which case errno will be set as appropriate.
//
// Examples
// RPI_serialOpen("/dev/ttyAMA0", 9600)
