I have near zero PDP-11 Unix experience, but I remember one flavor (BSD 2.11 ?)

I discovered working with Unix V6 on my '11/45 that its tty output driver is
hard coded to always cook bit 8 as a parity bit, for any character where bit 8
is not already set (see Lions, line 8522).

My earlier reply didn't make it to the list. Here it is:
In simh I am using an 11/53 cpu which has 2 serial ports and you do this :
sim> set tti 7b
which clears the higher order bit. In my configuration tti is the
console. With this set vi and man pages work as expected, more also.
