title: MSCOMM32.ocx usage causes Not Trusted Error
body: <p>I was using an Excel macro which uses mscomm32.ocx for communicating with the serial port. It was working fine until some one or two month back. Now when we try to run it again it is not working. When I try to load it, it says the "Subject is not trusted for the specified Action".
  Can any one help me out!?</p>
  
  <p>Thanks...</p>
