See An Gurux for an overview.

With gurux.serial component you can send data easily syncronously or asyncronously using serial port connection.

Open Source GXSerial media component, made by Gurux Ltd, is a part of GXMedias set of media components, which programming interfaces help you implement communication by chosen connection type. Our media components also support the following connection types: network.

With gurux.serial component you can send data easily syncronously or asyncronously.

We are updating documentation on Gurux web page.

You can get source codes from http://www.github.com/gurux or if you use Maven add this to your POM-file:

<dependency>
  <groupId>org.gurux</groupId>
  <artifactId>gurux.serial</artifactId>
  <version1.0.26</version>
</dependency>

Simple example

Before use you must set following settings:

• PortName
• BaudRate
• DataBits
• Parity
• StopBits

It is also good to add listener and start to listen following events.

• onError
• onReceived
• onMediaStateChange
• onTrace
• onPropertyChanged

GXSerial cl = new GXSerial();
cl.setPortName(gurux.serial.GXSerial.getPortNames()[0]);
cl.setBaudRate(9600);
cl.setDataBits(8);
cl.setParity(Parity.ODD);
cl.setStopBits(StopBits.ONE);
cl.open();

Data is send with send command:

cl.Send("Hello World!");

In default mode received data is coming as asynchronously from OnReceived event.

Event listener is adding class that you want to use to listen media events and derive class from IGXMediaListener.

    */
    @Override
    void onPropertyChanged(Object sender, PropertyChangedEventArgs e)
    {
		//Example port name is change.
    }      
}

Listener is registered calling addListener method.

cl.addListener(this);

Data can be also send as syncronous if needed.

synchronized (cl.getSynchronous())
{
    String reply = "";    
    ReceiveParameters<byte[]> p = new ReceiveParameters<byte[]>(byte[].class);    
    //End of Packet.
    p.setEop('\n'); 
    //How long reply is waited.   
    p.setWaitTime(1000);          
    cl.send("Hello World!", null);
    if (!cl.receive(p))
    {
        throw new RuntimeException("Failed to receive response..");
    }
}
