msmouse not recognized in guest

The msmouse option for emulating a serial mouse does not seem to work in a DOS guest. I'm on Windows 10 X64, I have tried launching qemu (commit d0cc248164961a7ba9d43806feffd76f9f6d7f41 but also way older) with: ./qemu-system-i386 -serial msmouse -fda mousetest.img ./qemu-system-i386 -chardev msmouse,id=msmouse -device isa- serial,chardev=msmouse -fda mousetest.img ./qemu-system-i386 -chardev msmouse,id=msmouse -device pci- serial,chardev=msmouse -chardev msmouse,id=msmouse -fda mousetest.img Then I boot FreeDOS (but regular DOS shows same behavior), start the CuteMouse driver and force the scan of a serial mouse with CTM /S. The mouse is never found. With other drivers (in the attachment), the mouse is probably not found but the driver is installed anyway, but it does not work (there's a MOUSETST in the same floppy; it works iwth CTM and PS/2 mouse emulation). Using a serial port sniffer inside the guest, it would seem that data is indeed transmitted. Setting a few printf in msmouse.c also confirms that the mouse gets initilized and starts transmitting data. However, it does not work...
