Summary: Heavy Weather runs too slow / possible serial port baud
                    rate issues?
           Product: Wine
           Version: 0.9.33.
          Platform: PC-x86-64
               URL: http://www.heavyweather.info/new_english_us/index.html
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-comctl32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When running HeavyWeather inside of wine - the app starts - but when the app
comes up - it uses 100% of the CPU.  And it's really really slow.  When the GUI
comes up - it makes requests via the serial port to get the data for about 15
different fields that are displayed.  With an older version of wine (same
hardware) - this took about 2 seconds to get all 15 fields.

Now, it takes about 5 seconds _per field_ to get the data.  Eventually, all of
the fields fill in - but CPU usage stays locked at 100% - and any interaction
that I try to have with the application is really slow.

The application then crashes within 3 to 4 minutes.

While the application is running, this is printed out on the terminal:

err:file:GetOverlappedResult PENDING status after waiting!
err:file:GetOverlappedResult PENDING status after waiting!
err:file:GetOverlappedResult PENDING status after waiting!

The trace (that I'll attach shortly) indicates a really slow baud rate has been
selected:

000d:trace:comm:dump_dcb bytesize=8 baudrate=2400 fParity=0 Parity=0 stopbits=1

The application doesn't provide any configuration for baud rate.

It's basically unusable in its present form - and this is a regression - it used
to run much better in wine.

On the mailing list Detlef Riekenberg indicated:
> If the App has no options to configure the Serial Port,
> it may use the default COM-Settings.
>
> Old Wine versions returned always 38400 as Baud-Rate and
> Hardware-Handshake for the Flow-Control.
> This was fixed recently.

Not sure if that has anything to do with the slowdown.
