"COM1" serial port: Access is denied"

Hi Guys:
I am trying to connect a null modem cable to COM1 (the only one I have) and get
the error msg:
"Unable to open the "COM1" serial port: Access is denied"

Any thoughts?

Thanks.  Jerry

Thank you for both suggested fixes.  But you got me thinking and after some checking it appears that COM1 was being used by Microsoft Mobile.  So, when I put the mobile device onto COM3, COM1 was released and I was able to access it.  Thank you both for responding.  Jerry
