Access to the port 'COM1' is denied
<p>I am tring to open the COM1 port but I am getting this error message "Access to the port 'COM1' is denied". Actualy, I am writing a program for sending SMS via net. I accept there could be an error, but "Access denied" error should not arised. Please give me any solution. If port requires any access privileges then how can I give that.</p>
