https://bugs.winehq.org/show_bug.cgi?id=40540 --- Comment #7 from henry(a)littau.org --- Hi Alex, On a slower computer I also see the timeout in WaitForMultipleObjects under Windows. That is likely an artifact of our little test environment, I have not seen this in real use. (Our devices run 9600 to 115200 baud and send 9 characters back, the test environment runs 2400 baud and sends 27 characters back once Windows gets around to switching tasks a couple times) Bump the timeout on WaitForMultipleObjects to 1500: switch( WaitForMultipleObjects( dwCount, hEvents, FALSE, 1500 ) ) //::WaitForSingleObject( m_ovWait.hEvent, dwTimeout)) This should get you past the Windows speed issue. I had no idea about wineg++, thank you, that is most helpful. This issue, BTW, is the same under Wine and OS X. Should I file a bug specific to OS X or can this one be tagged for both? I would also like to file a bug against WineHQ Buzilla because it thinks I spelled artifact wrong :-) Henry -- Do not reply to this email, post in Bugzilla using the above URL to reply.
