That's not a problem: 8bit-controls should only be used after
a S8C1T sequence has been issued, unless the terminal setup has
enabled 8bit C1 controls as default. See my comment in the sources.

I think we need to implement some IOCTL's and a userland (curses-based)
replacement for the setup of a VT terminal. Any volunteers?
BTW: setterm is problematic because it misuses control functions
allocated by the standards (both ISO and DEC) for entirely
different purposes!
