Windows API CreateFile / ReadFile / WriteFile do overlapped I/O for all
devices that support it. COM port does support it (though with Ada tasking
it is simpler to do input and output from two separate tasks, if
full-duplex I/O is all what you need. I don't know, maybe, you want to
handle 100+ ports, then possibly overlapped I/O would make sense.) Anyway,
you don't need any special bindings for doing overlapped I/O beyond Windows
API.
