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: [e-mail]
        ReportedBy: [e-mail]

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:
> 0009:Call kernel32.WriteFile(0000005c,42b938cc,00000001,4087fcb4,00000000)
> ret=00437de2

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.
