There was work done in the linuxolator to make this possible. There =20 was also some work done in the TTY code, to seperate COMPAT_43TTY and =20 COMPAT_43. I don't know if this is already done in 5.4 or 6.1. If =20 there exists COMPAT_43TTY and you don't need the linuxolator, you can =20 give it a try. Removing COMPAT_43TTY will break some ports according to phk.
