Close comport after uploading

[Qynx]

I have a problem on my current desktop PC with windows 8.

If I use the USB on the front Windows is not see the FTDI chip.
But if I use the USB on the back side windows is installing the drivers and
everything seems ok....

But,  after uploading a sketch the COM Port is not closed.

After a timout from AVRdude the port is not closing. and Wiring keeps displaying

Uploading...

So I have to disconnect the board so windows is closing the Comport and Wiring say there is a serial error.

After that and reconnecting I can open the terminal window and by closing the terminal the
COMport is closed.

It looks a problem between AVRdude and wiring.

I'm using Windows 8 on a 64 bit system

Hi there!

What board and which settings do you use (bottom right of IDE)?

Hi Brevig,

I use a V1.0 compatible board  atmega 128 and FT232RL
I use this  board with Mega128  and Mega1281 or mega2561

Works great, but not on my new windows 8 desktop.

Ok,

Does the Serial Monitor show up?
If you use Serial.begin() in your sketch Wiring will try to open the Serial Monitor.
If you want the COM port to be closed you should try to exit from that window as it should close the COM port.

I'm on Windows 8 x64 as well, and FT232RL based boards have worked fro me.
Maybe you could copy and paste the error messages you get?

Brevig,

The last Message is:

Uploading.....


And it looks he's ready with uploading,  I try to make a small movie tomorrow  so its more clear wat the problem is.

hi, please also note there is a new version of the driver at http://www.ftdichip.com/Drivers/VCP.htm download and launch the exe file, I just tested it with Windows 8 and works fine.
