Of course, the switch in .login is useless if you log in on a network
port.  I have my .kshrc prompt me for the terminal type.

It doesn't work.

The TERM variable is set to a name that has a good terminfo entry, but
vi still won't come up in full-screen mode if I open the connection with
rlogin.

When I use telnet vi works fine.
