Rob Pike solved the terminal driver problem very nicely -

HE EXPUNGED THE DRIVER!

With the Blit, all the user-interaction cruft goes in the Blit
where you have a CPU and operating system dedicated to doing
high-quality user interaction tasks.  The Unix machine is releaved
of this onerous chore and is left to do what it does best: compute!
(No one can claim the VAX is well-optimized for character-based
interrupts and context switches.)

The only problem with this solution is its cost -
but you get what you pay for.
