I developed an application for Pocket PC. It uses the inbound COM port of
the Bluetooth Serial Port service. With Bluetooth for Windows CE(BTW-CE)
Version 1.4.1 Build 4, I push the power button to turn off the iPAQ while
the application is running and the COM port is still open. But push the
power button again will not turn on the iPAQ, I have to soft reset the iPAQ
to bring it up.

But with Bluetooth for Windows CE(BTW-CE) Version 1.4.1 Build 3, it doesn't
have this problem. I can turn the iPAQ on and off with my application
running. Is there anything changed in Build 4? Should I close the COM port
when the iPAQ is turned off?

Thanks
