how to use TestSerialWrapper?

[robbStarkTFG4]

can you add an example showing implementation of interface SerialPortWrapper?.

[terrypacker]

Here is one that we use inside of Mango Automation.

You will also need to refer to the abstract class SerialPortProxy and one of its concrete implementations JsscSerialPortProxy

Unfortunately, there is little documentation on this, but here's another one I created using JSSC as the underlying Port implementation.

import com.serotonin.modbus4j.serial.SerialPortWrapper;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.InputStream;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.List;

/**

 */
public class SerialPortWrapperImpl implements SerialPortWrapper {
    private static final Logger LOGGER = LoggerFactory.getLogger(SerialPortWrapperImpl.class);
    private final SerialPort port;
    private List<PortConnectionListener> listeners = new ArrayList<>();

    public void addPortConnectionListener(PortConnectionListener listener) {
        listeners.add(listener);
    }

    public SerialPortWrapperImpl(String portName) {
        port = new SerialPort(portName);
    }

    @Override
    public void close() throws Exception {
        port.closePort();
        listeners.forEach(PortConnectionListener::closed);
        LOGGER.debug("serial port " + port.getPortName() + " is closed");
    }

    @Override
    public void open() throws Exception {
        port.openPort();
        port.setParams(this.getBaudRate(), this.getDataBits(), this.getStopBits(), this.getParity());
        port.setFlowControlMode(this.getFlowControlIn() | this.getFlowControlOut());

        listeners.forEach(PortConnectionListener::opened);
        LOGGER.debug("serial port " + port.getPortName() + " is open");
    }

    @Override
    public InputStream getInputStream() {
        return new SerialInputStream(port);
    }

    @Override
    public OutputStream getOutputStream() {
        return new SerialOutputStream(port);
    }

    @Override
    public int getBaudRate() {
        return SerialPort.BAUDRATE_9600;
    }

    @Override
    public int getFlowControlIn() {
        return SerialPort.FLOWCONTROL_NONE;
    }

    @Override

hi. i am using rs232 interface with rs485 converter ic and i need to down rts pin. do you know how i can do this with jSerialComm library and why you wrote both getflowcontrol override functions flowcontrol_none ?

[SharPeiDog]

本人小白一个 ，有什么不完善的地方希望大家可以指出，以下只是我自己的做法。 首先，你需要下载一个额外的支持Java串口通信操作的jar包。 地址： http://files.cnblogs.com/files/Dreamer-1/mfz-rxtx-2.2-20081207-win-x86.zip（32位）

http://files.cnblogs.com/files/Dreamer-1/mfz-rxtx-2.2-20081207-win-x64.zip （64位）

.dll文件放在jdk路径下（xx\jre\bin） .jar 文件导入项目 具体操作参考： http://www.cnblogs.com/Dreamer-1/p/5523046.html

接下来是我的 SerialPortWrapper 实现类
