Bug ID: 37115
           Summary: Calling ReadFile from WINBASEAPI (WinBase.h) with zero
                    read length causes hang
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

Our software connects to a serial device using USB-serial adapters. In the
process of attempting to create a wrapper for use on OSx, I discovered a hang
when I attempted to connect to the device under Wine that does not occur under
Windows.

I have tracked it down to the WINBASEAPI ReadFile. Under Windows, if a zero
value is passed as the length to read, it handles and returns zero. Under Wine,
it causes a "black box" (meaning I can't trace it) hang.

I have worked around this in my code by including a return on zero value for
the length, however believe it may be responsible for other serial issues I
have seen in researching this problem.
