Serial Port Communication with Java

Here am showing the simple serial port communication program,

here i will show you how to get list of all available serial and parallel ports available

FIrstly,By default java does not contains javax.comm package so we need to install it into our pc java follow this link to know

How to add javax.conn package to java

after adding this package to the java

just run the below code to get available serial and parallel ports

[sourcecode language="java"]
package in.mjtech.serial;

import java.util.Enumeration;

import javax.comm.*;

public class ListSerial {

public static void main(String[] args) {
// SerialParameters params=new SerialParameters();
// System.out.println(CommPortIdentifier.PORT_SERIAL );
Enumeration portList = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
CommPortIdentifier portId = (CommPortIdentifier) portList
.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_PARALLEL) {
System.out.println(portId.getName()+ " is parallel port");
} else if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
System.out.println(portId.getName()+ " is serial port");
}

}
}
}
