Writes NumberOfBytes data bytes from Buffer to the serial device.

The number of bytes actually written to the serial device is returned.

If the return value is less than NumberOfBytes, then the write operation failed.

If NumberOfBytes is zero, then return 0.

@param NumberOfBytes Number of bytes to written to the serial device.

@retval 0 NumberOfBytes is 0.
|

@retval >0 The number of bytes written to the serial device.

If this value is less than NumberOfBytes, then the write operation failed.
