serial port trouble on Win10

[Ulrich Schmidt <u.sch.zw@...>]

Hi all

My windows10 app try to comunicate with some external hardware via a
serial port

I use Lua5.3(gcc_64)+iup(precompiled-mingw6_64)[1] to build my Windows10
App. So far so good.
I can open the serial port via io.open() but this approach works in
buffered mode and my short messages get stuck in the transmit buffer.
2.try: I used winapi.open_serial() but this function silently craches my
app in case the filename is correct.

Now my questions:
Anyone tried winapi.open_serial()[2] on Win10? (mingw6_64)
Can anyone suggest a solution/lua-module, that works out of the box?

Thank you all.
Ulrich.
