Are you checking for errors? Please show a code snippet of what you are actually doing. Rather than using ClearCommError(), why not just read immediately after writing? You are already expecting a byte to be written, so just read immediately and let the reading block until the byte actually arrives. It also looks like you are using overlapped I/O, which played directly in my suggestion as well, since ReadFile() will return immediately and then you can use WaitForSingleObject() to wait for the reading to signal the event object that you place in your OVERLAPPED structure.
