WaitCommEvent timeout

When I use the WaitCommEvent() API on non-overlapped serial operations, I get an infinite wait state whenever the event I am concerned with doesn't occur.

I am thinking if I could implement a timeout using WaitCommEvent() so that even if the event I am waiting for doesn't occur, my program will not hang and report a timeout instead.

How do I do this?

I cannot find any direct solution.
Maybe SetCommMask() can help for a workaround because it makes WaitCommEvent() return immediately, so you install a timer that calls it after some time.
