Can you share your code?
I was try to connect blink to laptop I able to connect cloud and is working well in my Dell Laptop. When I connect my DELL PC I received the error message finally I found this trouble. So what I should do for this error message? My operating system in pc is Window7 64bit machine.
Thank You
I doubt very much if your Arduino is actually connected to Com1 on your PC.
Look at the serial ports in Device Manager without your Arduino connected. You probably already have a Com1.
Now connect your Arduino and see what additional Com port appears. This is the one to use for your connection command/script.

The communication com port in arduino is all correct , in my laptop is working well the same program. in my PC window7 is not works ,any how i will do troubleshooting to makes works.
