title: Javax.comm API on 64-bit Windows
body: <p>I am using the javax.comm API to help my program communicate with hardware over serial port. I am using the Windows 7 and NetBeans IDE 9. </p>
  
  <p>I used the common Java program to check the available ports on my PC. The program compiled and ran without error. However it returned nothing. </p>
  
  <p>What can I do to use the javax.comm API on Windows? It seems win32com.dll does not work with a 64-bit operating system.</p>
