This is a Wine regression. Reading documentation/cvs-regression
could help I think.

About your trace, it shows no obvious problem : the port is
opened, and Wine/the app writes many bytes to it (handle 244).
As the comm trace don't report the success of WriteFile, it's
unclear if this fails. Using +relay trace could get you this
information (WriteFile returns 0 if it fails)

Comparing the trace for the older (working) Wine version with 
the (failing) current version is often interesting, too.
