For the socket based I/O stream implementations (IrDA and bluetooth) the serial communication specific functions are meaningless. Implementing them as no-ops allows the dive computer backends the call the I/O stream functions unconditionally. This is important for the bluetooth implementation, because bluetooth enabled dive computers will be able to use both the native bluetooth communication and the legacy bluetooth serial port emulation.
