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: https://github.com/CyberShadow/misc/blob/master/pq321q.d 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!

Posted in reply to braboar | 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. |
