can not create 4 serial port on window (guest os)

qemu ver: 2.1.2-Latest

guest os: window 7 64bit with 2 cpu 

problem: when qemu start with 4 serial port, on linux(rhel 7) guest os, /dev/ttyS0-4 is work fine.  but on window 7 guest os, only show com1,com2 in device manager, how to get com3 & com4 ?

qemu cmd:
 -chardev spiceport,id=charserial0,name=org.qemu.console.serial.0
 -device isa-serial,chardev=charserial0,id=serial0
 -chardev spiceport,id=charserial1,name=org.qemu.console.serial.1
 -device isa-serial,chardev=charserial1,id=serial1
 -chardev spiceport,id=charserial2,name=org.qemu.console.serial.2
 -device isa-serial,chardev=charserial2,id=serial2
 -chardev spiceport,id=charserial3,name=org.qemu.console.serial.3
 -device isa-serial,chardev=charserial3,id=serial3

Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU and Windows? Or could we close this ticket nowadays?
