Let me guess ... you're using GCC 3.4.x, right? To compile QEMU with
MinGW you need to use GCC 3.3.x, otherwise op.c will get overoptimized
and QEMU can't handle that...

Hi,
Here are patch for serial port support(partial; linux host only). You can
invoke it by adding sth like "-serial /dev/ttyS0" in arguments to let qemu
using host's serial port as its serial port. qemu will change host's serial
port setting(baudrate, databits, stopbits, parity) when guest os change them.
In my test, I use minicom's zmodem to send file. When sending file to qemu,
things works fine. When sending file from qemu, file can be sent completely,
but qemu gives many warning saying "serial8250: too much work for irq4".
I has also worked on serial port support for windows host, but my build of
qemu always crash, althrough I have tried different method: cross-compile
using i386-mingw32msvc; mingw/msys. If anyone who has build qemu windows
port can teach me about it, I will try to finish my windows support when I
get time.
Any comments/tests are welcome.
Best Regards
Cai Qiang

Oh, yes, I check and find my cross-tools i386-mingw32msvc is gcc version 3.4.1
(mingw special), and my windows mingw is gcc version 3.4.2 (mingw-special).
Thanks a lot and I will try GCC 3.3.x.

Hello
I have tried to debug the nasty problem, that I loose the keyboard
input in QEMU, when using FreeDOS with HIMEM, EMM386 and FDAPM. I
found a "raise_exception 0xd" in the debug log. I think this is a GPF.
If I use HIMEM and FDAPM, it works fine.
Because HIMEM, EMM386 and FDAPM is working on a real machine, could
there be an error in QEMU ? The interesting point is around the "hlt"
command.
Andreas
========================================
OK: HIMEM, FDAPM
