Re: Ethernet cable presence detection (WinCE 5.0)

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The controller has to notify the driver and the driver has to notify the OS.
This *is* commonly done with an interrupt and I'd be surprised if the
controller didn't *offer* that functionality. Since I know nothing about
that driver, though, it doesn't mean that it's using that feature.

Hello all,
I have a PocketPC device which consists of PXA255, LCD and Davicom
9000E ethernet controller, running WinCE 5.0
I am having a problem that the WinCE doesn't recognizes the
disconnection of the ethernet cable.(The icon the the right-lower
corner doesn't become red)
I put a scope on the interrupt(ISA INT) line from the Davicom to the
PXA255 and no interrupt occurs when the cable is disconnected.
I took a look at Intel's reference design and BSP, and i saw the same
connections.

How than the internet controllers inform WinCE that the cable was
disconnected?
Can i check in manualy in anyway, and inform WinCE of that?

Thanks,
Oren.
