Verify bit-timings for non-exclusive access to interface thru COM server?

[RudolphRiedel]

My supercan.c module tried to get exclusive access to the COM server, sort of. It simply refused to go further if AcquireConfigurationAccess() failed to return successfully.
Ok, good, only one application at the time should be allowed to configure the bus timing.

So the supercan.c module is now a little more relaxed about AcquireConfigurationAccess() - and it works now when the interface already is in use.
However, what does not seem to be possible is to query the settings that are in use, so there apparently is no way to verrify that the intended use of the channel matches the current settings?

I had an idea and output the timing values returned by GetDeviceData() if AcquireConfigurationAccess() fails.
I hoped the timing values would reflect the current setting if changing the setting is not possible.
But unfortunately this is not the case, so still no idea on how to verify the bit timings.
