Thanks for the pointer. Unfortunately, the document does not mention
about the behaviour of WriteConsoleInput() in the win32-inpu-mode.

I expected that ReadConsoleInput() returns the INPUT_RECORDS which
WriteConsoleInput() sends. However, that does not seem true in this
mode.

There is no other means than modifying the source code of cygwin1.dll
and rebuild it. I already tried that and the problem disappeard.
