Status in QEMU:

Bug description:
  Hi All

  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.
