I have the latest weeks had fun converting the uba code to use the
bus.h-interfaces instead, so that Qbus-based mips machines can make
use of it also. Converting the MSCP code was rather straight-forward,
so also the tty-device controllers. But the DEQNA code was anything
but straightforward :-) It ended up with a complete new device driver
that for me seems to work very well. It also gave some speed improvements,
about 600k/s am I able to get through it compared to 300k/s before,
on a MV3 I have.

I will soon switch over so that the default uba code is the new code.
