[Bug 827] New: - Running Agfa Photowise under Wine

Summary: Running Agfa Photowise under Wine
           Product: Wine
           Version: 20020605
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: wine-files
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When Agfa Photowise tries to comminucate to the digital camera connected in
/dev/ttyS0, it tries to flush all file buffers using FlushFileBuffers()
Under linux, flushing /dev/ttyS0 seems to fail and FlushFileBuffers() will
return FALSE, which in turn causes Photowise to think that communication has failed.

Changing FlushFileBuffers() in files/file.c to always return TRUE, will make
Photowise to work perfectly, and finally I can use my old Agfa CL50 at full
115200 speed under linux.

The change I did was:
BOOL WINAPI FlushFileBuffers( HANDLE hFile )
{
    BOOL ret;
    SERVER_START_REQ( flush_file )
    {
        req->handle = hFile;
        ret = !wine_server_call_err( req );
    }
    SERVER_END_REQ;
    /* do not ever fail :) */
    return TRUE;
    /*return ret;*/
}

But this is not good, there probably should be some knowledge in the hFile,
which  would tell the wineserver that this is a serial device and flushing
should be done in some other way (or not at all?).
