In other places the symlink method seems to be limited from 1 to 9 (e.g. QueryDosDeviceW)

I think get_default_com_device() isn't a normal way to use com ports in Wine.
For example, I have /dev/ttyS0 to 31, most likely announced by my laptop motherboard, but would never intend to use those ports, which are not wired out.
Normal usecase would be to plug in a USB-Serial-Adapter and make a symlink to e.g. /dev/ttyUSB0
