If you need more detail than what is presented in this quick review, then you should check the references listed at the end of this chapter.ġ. There are a number of excellent references for Java. We hope to have shown you a wide sampling of the methods and techniques you will need to assist you in developing robust programs for communicating with your network-enabled devices. While some of these examples have been fairly detailed, they are a far cry from a full tutorial on each topic. This can be dealt with by simply implementing a buffer in your program and each read appends the data to the buffer. In either case, this is probably typical for an event listener: you will not get everything you are expecting in one event. This could be the result of many different things, such as the process being interrupted by another event or the data being sent slower than it is being read. Notice that not all of the data is read in at the same time. Once again, we want to call your attention to the output from this program. Messagereceived = new String(readBuffer) Int numBytes = inputStream.read(readBuffer) In the case of the event being SerialPortEvent.DATA_AVAILABLE we then read from the serial port's input stream. The serialEvent listener is a simple switch that examines the event type and reports that. Public class SerialLoopTest implements Runnable, SerialPortEventListener Īs soon as the data is sent, the SerialEvent event listener is triggered.
