SerialPort

[braboar via Digitalmars-d-learn]

I am going to play with serial port read/write, so I fetched 
serial-port. After that, I wrote simple program:

    auto port_name = "/dev/ttyUSB1";
    auto reader = new SerialPort(port_name);
    reader.dataBits(DataBits.data8);
    reader.stopBits(StopBits.one);
    reader.parity(Parity.none);
    reader.speed(BaudRate.BR_230400);
    string[] income;
    reader.read(income);
and the result is
serial.device.TimeoutException

Can anybody give me a guide of using serial port?

And one more question: how to outline code blocks? ''' or --- 
can't help me.
