The following ideas are *unsupported* by Digital ;^)

You could try setting up /etc/ttys *not* to use

    :0 "/usr/bin/login -P /usr/bin/Xprompter -C /usr/bin/dxsession"
    none on secure window="/usr/bin/Xqvsm -fd 75 "

For the VAXstations, try:

  ttyv0 "/usr/bin/xterm -L -sb -rv -geometry =80x24+195+275 -d unix:0"
    xterm on secure window="/usr/bin/Xqvsm -fd 75 0"

Logging via an xterm is not a good idea, so try something like xdm or xsh.
The -L option is unsupported .

To get the same effect on RISC (DECstations) machines,  try:

mv /dev/ttypf  /dev/ttyv0
mv /dev/ptypf  /dev/ptyv0

The end result should make it work just like the VAXstation /etc/ttys entry.
Swapping different/matching pairs of tty and pty should work fine.
