Hi All
I also meet this issue.
I have two computer, one is Win7 32 another is Win7 64, Both computer meet
this issue.
My QEMU version is qemu-w32-setup-20160215
I want used EDK2 OVMF with Intel UDK Debugger tools to do source level debug
I had install com0com Virtual Com Port, and set COM3 connect to COM4
Intel UDK Debugger tools used COM3
QEMU run OVMF used COM4
First execute Intel UDK Debugger tools, then launch QEMU
C:\Program Files\qemu\qemu-system-x86_64.exe -bios
"C:\EDK2\Build\OvmfX64\DEBUG_VS2010\FV\OVMF.fd" -serial COM4
Then QEMU crashes on stratup
I have do some experiment
Execute terminal tool Tera Term and used COM3
launch QEMU and used COM4
C:\Program Files\qemu\qemu-system-x86_64.exe -bios
"C:\EDK2\Build\OvmfX64\DEBUG_VS2010\FV\OVMF.fd" -serial COM4
This is fine and i can see OVMF trace log on terminal
But if i press "Down" key on terminal, then QEMU crashe
It's caused by terminal send data("Down" key) to QEMU
Have somebody can share some information about this?
Thanks a lot.

Title:
QEMU crash after sending data on host serial port
Status in QEMU:
New
Bug description:
Good morning,
I'm using QEMU for Windows last version.
The host system is Windows 7 64bits.
I'm excuting the following statment :
qemu-system-x86_64w.exe -hda debian.img -m 256 -net nic -net
tap,ifname=TAP32 -soundhw all -serial COM9
Qemu starts the emulated Debian and it runs correctly.
If I try to send data from Windows using COM9 to QEMU (both "real" or
emulated by the COM0COM driver), QEMU crashes. Windows dump available if
required.
If I try to send data to /dev/ttyS0 (that should be the Linux side of COM9)
from Debian, again, the wirtual machine crashes.
More details if necessary
Best regards
U.Poddine
