CreateFile coredll.dll freeze!

Hi,

I've found what I think is a bug in PocketPC 2005 that frezzes the entire
device(!) I've isolated the problem to coredll.dll.

I'm using CreateFile to hook up the 'COM1:' (the connector on the bottom of
the device) on a hp hx2490 running PocketPC 2005.

The problem occurs if I connect the com-port to my PC and start sending
characters from the PC to the device and then calls CreateFile, the device
freezes!

Is there anyone that have had the same problem?
Does anyone know how to report a bug to Microsoft?

Regards
/Mats

Are you sure it is CreateFile that causes the lockup and not a buffer
overflow?

I seriously doubt it's a bug in CE or Windows Mobile. If anything it would
be a driver issue, which comes from the device OEM..

Hi,

TJ, Yes, I'm quite sure that it is the CreateFile call that freezes.

Chris, you are probably right, it is probably a malfunctioning serial
driver, thanks for pointing that out to me!

I'll go after hp instead!

Thanks!
