[net.periphs] Trouble with Versatec 121 and UDA controllers on 750 UNIBUS

I have tried to install a versatec 121 controller on the same UNIBUS
with a UDA50 controller.   There seems to some kind of timeout problem
in that vtroff jobs get about half way through (print jobs too), and
they just stop.  The rvcat is hung and can only be killed by turning
off the V80.  Has anyone else experienced similar problems?  Do you
know a fix?  I have tried everything I can think of:  putting the 121
first on the UNIBUS, changing the timeout value on the UDA50 from 0
to 6.5 to 10 micro seconds, changing the priority of the 121 from 4 to
5.
