Details:

I have an Arduino Micro with Optiboot-Bootloader and I can upload sketches
with AVRDude over TCP on Linux.

I tried to use AVRDude 6.3 on Windows but AVRDude does not correctly drain the
read buffer and so AVRDude gets confused.

In ser_win32.c there is a special version of ser_recv() for TCP-connections,
but ser_drain() uses the version for serial connections. But it doesn't work.

I get the output as attached.
The read buffer isn't drained so avrdude recives the incoming data from the
initial getsync later.
