I don't have a fix for
WaitCommEvent() does not return ERROR_INVALID_PARAMETER without ovl
And I had no plans to do so nor did I claim.
I removed the side effect that this test makes the next test fail which tests
the EV_TXEMPTY handling even if that it would work perfectly.
test A fails on wine and this influences test B in such a way that it will
always fail, too.
I remove this dependency.
Now test B succeeds. This is not because I worked arround a wine-bug in what B
should test but because wine behaves correctly in this test.
And test A still fails.
