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!
