function res=open_serial(nHandle, nPort,baudrate)
// Command to initialize the serial port which is connected to Arduino
//
// Calling Sequence
//     res=open_serial(nHandle, nPort,baudrate)
//
// Parameters
//     nHandle : Board number, reserved for future use. For this version, any number would do
