Debug Log

It is shown on Wine 1.0.1, 1.1.38, 1.1.39 (Other versions were not tested) \
Ubuntu 9.10 x86

After opening application COM port through MSCOMM32.OCX there are 100 % of
loading CPU, even at absence of data exchange. Thus the exchange through port
goes normally. After closing COM of port loading on CPU falls down.

See WINEDEBUG = " + comm " log in attach.

How much I know, a problem because of with incorrect realization of function
WaitCommEvent () in Wine.

This is your friendly reminder that there has been no bug activity for 2 years.
Is this still an issue in current (1.7.7 or newer) wine? If so, please attach
the terminal output in 1.7.7 (see http://wiki.winehq.org/FAQ#get_log).
