Hi,
I've managed to get a BSD 2.11 root filesystem onto my 11/73 via VTserver
and I am preparing to use vtc to transfer the /usr components.
Currently when I boot, I start off with my terminal set to 19,200 baud
8-N-1 but once BSD has booted I have to switch to 19,200 7-E-1
Can anyone tell me why this is happening and how I fix it so the setting
remains on 8-N-1? (stty?)
Also, if I can't fix this, will vtserver/vtc run on 7-E-1 comms?

The PDP-11s tend to like 8n1, but UNIX used to prefer 7e1. I got
tired of 2.11BSD behaving like this, so I changed it thus (note that
the relative directory names in the patch headers are probably not
relative to the same place; you'll have to figure it out):
