Yep, that's documented in 
http://minnie.cs.adfa.edu.au/Vtserver/vtserver/vtreadme.txt as follows:

   The file .vtrc is the server's configuration file. Lines beginning with
   hashes are ignored. The first (non-hashed) gives a shell command to set the
   correct speed and parity of the serial line. The second line names the
   serial device. Remaining lines name the fictitious tape's records, and
   should be tinyboot, copy, and the name of your disk image.

Thanks, can you suggest changes to the above document which would help
to clarify this?

Also, Fred van Kempen has added commands to send down the bootstrap
code if the PDP-11 has ODT. I'll add this to the server once I get the
code from Fred.

Thanks Ian, yes I'm always happy for feedback. You might also try the
two Ultrix RL02 images that Bill Gunshannon also donated to the archive,
as he booted these on an 11/23 ok.
