A reboot fixed it. I guess a previous crash maybe left the com port in a bad state.

I am running a loop on a thread for each COM port, using non-overlapped I/O. It's primitive, but it works well enough. Well, it does now. It was freezing up on the call to FileOpenW(L"\\\\.\\COM25",...) but a reboot fixed it and it's all working great now.
