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: wine-bugs at winehq.org
ReportedBy: vortex1111vortex at gmail.com
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.
