vi missing commands on 3b1

[Thomas J. Pusateri]

Does anyone know why ctrl-^ doesn't work with the unix-pc 3.51 version of vi?
Once you specify an alternate file to edit, it is supposed to switch back
and forth between the two files. It works fine on every other System V and
BSD version of vi I have ever used, but for some reason it has been
disabled on the unix-pc.

Also I have noticed that I cannot directly enter a '@' character on the
unix-pc version of vi. I have to enter a ^V first and then the '@ character.
Who's been adding features (?) to vi?

Just curious,
