           Summary:  ERROR_IO_PENDING when reading from serial port
           Product: Wine
           Version: 20040505
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P1
         Component: wine-kernel
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: lhouk(a)lesliehouk.com

I've got an old digital camera, an Olympus D-300L, that communicates with the
computer via a serial cable.  It uses a Win95 application, C-W95.exe, to make
the connection.  I've used this application successfully under Win98SE and
Win2K, but I can't make it work under Wine.  The program starts fine, but
insists it can not find the camera.

I posted this problem previously in the Usenet group
comp.emulators.ms-windows.wine, where Rein Klazes was kind enough to help me
troubleshoot.  He determined that WriteFile() was failing with error code 0x3e5,
ERROR_IO_PENDING.  The specific debug log entries he identified as relevant are:
...

Note that this is bug report may be the same issue as reported in bug #469,
which was just changed to status: resolved due to inactivity.  Speeddymon asked
that a new bug report be opened on this issue, so I am doing so.

The original Usenet thread I started when I originally ran across this bug can
be viewed at

if anyone needs or wants to examine it.  Other Usenet threads that appear to
deal with the same bug (and some of which also propose actual code fixes) are:
