Try reassigning your com to 5 or under. The text says com13 but the display shows com14. As I understand, the drivers don't like higher com assignments than com5.

Hi Quinnifir,

The error you are getting means that either you don't have permissions to open up the serial port, or you have entered the wrong serial port. If you are sure you have reassigned it to a number lower than 5, and have double checked on the device manager that you have the right COM port, then try opening up the command line as administrator. This can be a bit tricky on Vista (never tried it on Windows 7). I think if you use the start menu to search for the cmd program, then the command line launch icon comes up in the menu, you can then right click that and click open as administrator. Let us know if that gets it to work.

I haven't found a way in W7 yet but will keep trying. XP still used the same GUI as the older versions and gave a little control. W7 was written to expect everybody to be an idiot so it tries to keep control of things. (IMHO)

Glad you got it Q, I take it that you found that you need to change the com port in more than one place.

Quinnifir,

What was the solution to your problem? That way if others with the same problem come across this, it may help the solve their issues as well. Plus, I don't thing I ever saw from you which version of windows you were using. I'm assuming 7 based on Humberto's remarks.

I'm getting the same exact error message (even when reassigning the com to 5 or under). I have W7 -- are there any solutions to this problem yet?

Thank you, Geeta

Hi Geeta,

Plenty of people have gotten their kit working on Windows 7. Which version of the driver are you using? Most people I believe had had the most success with this driver if the one linked to from the downloads section had issues.

It is definitely a good idea to try the port that your computer assigns to the device first before trying to change it. If you are getting the cannot find port error it might mean you don't have enough privilages to open it, you can try opening the command line as administrator to see if that does the trick.

Let us know what you find.

Hi Humberto,

Thanks for the quick reply. I opened the command line on w7 today, running it as administrator, and it worked on w7.

Btw, I got the temperature sensor project working on a mac yesterday -- it was loads of fun!

Thanks again, Geeta
