This not only builds but works on ppc64. I tested this on my system with serial ports in use using the below program:
$ cat Main.java
import gnu.io.*;
import java.util.*;
public class Main {
/**
* @return A HashSet containing the CommPortIdentifier for all serial ports that are not currently being used.
*/
public static HashSet<CommPortIdentifier> getAvailableSerialPorts() {
HashSet<CommPortIdentifier> h = new HashSet<CommPortIdentifier>();
Enumeration thePorts = CommPortIdentifier.getPortIdentifiers();
while (thePorts.hasMoreElements()) {
CommPortIdentifier com = (CommPortIdentifier) thePorts.nextElement();
switch (com.getPortType()) {
case CommPortIdentifier.PORT_SERIAL:
try {
CommPort thePort = com.open("CommUtil", 50);
thePort.close();
h.add(com);
} catch (PortInUseException e) {
System.out.println("Port, " + com.getName() + ", is in use.");
} catch (Exception e) {
System.err.println("Failed to open port " + com.getName());
e.printStackTrace();
}
}
}
return h;
}
public static void main(String[] args) {
for (CommPortIdentifier element : getAvailableSerialPorts())
{
System.out.println(element.getName());
}
}
}
$ javac -cp /usr/share/rxtx-2/lib/RXTXcomm.jar Main.java
$ java -Djava.library.path=/usr/lib64/rxtx-2 -cp .:/usr/share/rxtx-2/lib/RXTXcomm.jar Main
