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.

Here's a program I wrote (after lots of trial-and-error) to 
control my monitor through an USB serial-port adapter:

Hope this helps.

here is my code really works:

com is `reader` object in your code.

```
     void writeBytes(ubyte[] arr)
     {
         com.write(arr);
     }

     void serialThread()
     {
         ubyte[500] buff;

         running = true;
         while (running)
         {
             string str;
             size_t readed;

             try
             {
                 readed = com.read(buff);
                 // if (readed > 0) {
                 //writeln("com port readed " ~ 
std.conv.to!string(readed));
                 str = cast(string)(buff[0 .. readed]).idup;
                 // Don't use writeln for console or string serail 
application.
                 write(str);
                 // }
             }
             // must catch for continous reading, otherwize, com 
port will block.
             catch (TimeoutException e)
             {
             }
        }
     }
```

thanks!

For me 
https://www.virtual-serial-port.org/products/serialmonitor/ is an 
ideal way to track down problems that may occur during 
application or driver development, testing and optimization of 
serial devices and i use this soft all time.
