Hi there,
Try this:
ports = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
if (portId.getName().equals("COM1")) {
/*Rest of Code*/
}
}
}
Regards,
Andrew

hi,everyone
Recently ,i found a strange problem.
I wrote a java file to print all the port on the command line. The source
code i attached below:
*import java.util.*;
import java.io.*;
import javax.comm.*;*
*public class listenraw {
public static void main(String argv[]) {
new listenraw();
}*
* public listenraw() {
CommPortIdentifier portId;*
* Enumeration ports = CommPortIdentifier.getPortIdentifiers();*
* if (ports == null) {
System.out.println("No comm ports found!");
return;
}*
* // print out all ports
System.out.println("printing all ports...");
while (ports.hasMoreElements()) {
System.out.println(" "
+ ((CommPortIdentifier) ports.nextElement()).getName());*
* }
}
}
*
The result was :*printing all ports...* It meant*
ports.hasMoreElements()*return false.
But from the device manager i found there are COM1 and COM2 occurred.
Can anyone tell me how can i solve the problem.
