Library provides simple non-blocking work with serial port for Posix and Windows.

Simple usage:

auto com = new SerialPort("/dev/ttyUSB0", 19200);

// setting parameters example
com.config = SerialPort.Config(9600, DataBits.data8, Parity.none, StopBits.one)
com.set(19200).set(DataBits.data8);
com.stopBits = StopBits.two;
// set 9600 baudrate, 8 data bits, no parity and one stop bit
com.set("9600:8N1");

// non-blocking write -- return writed bytes count at the first onset
auto cnt = com.write(someDataArray);

// non-blocking read -- return data in system serial port buffer
auto res1 = com.read(bufferForReading);
// res1 is slice of bufferForReading with readed data

Warning: unix systems allow only standard speeds

[0, 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400]

Example usage: monitor

If you want use basic read/write loop you can use SerialPortBL class.

//                                                      vibe.core.sleep for example
auto com = new SerialPortBL("/dev/ttyUSB0", "9600:8N1", sleepDelegate);

//                            write timeout
com.writeLoop(someDataArray, 500.dur!"usecs");

//                                          read timeout    frame end gap
auto res2 = com.readLoop(bufferForReading, 500.dur!"msecs", 20.dur!"msecs");

At expiration of write timeout throws TimeoutException.

At expiration of read timeout throws TimeoutException if no bytes readed. If readed bytes count != 0 wait frame end gap and if no new bytes return readed.

Reading and writing loops algorithms use Fiber.yield if available, or Thread.yield otherwise. If you want redefine this behavior, you can set void delegate() yieldFunc field of SerialPort through ctor or directly.
