Howdy,
Just forwarding to the list... in bug 3002 http://bugs.winehq.org/show_bug.cgi?id=3002 the reporter has found a regression in serial port handling, and narrowed it down to this CVS commit from January: http://www.winehq.org/hypermail/wine-cvs/2005/01/0378.html Log message: - got rid of include/async.h - fixed some overlapped issues in socket handling - moved kernel32.CancelIo implementation to ntdll
The bug includes a description of where to get the app and how to run it.
