   It also won't work.  The standard (Berkeley) interpretation of this is
   that when the rsh binary is run as a program not named "rsh" (i.e.  with
   argv[0] something other than "rsh") it takes argv[0] as a machine name
   to connect to.  Thus you can link "rsh" to "dialogic" and type

The rsh in the 386/ix 2.0.2 release does allow calling it "rshell" or
"remsh" for compatibility with a couple of other packages and for
people who want /bin first in their search path and don't want to
change /bin/rsh to some other name.  Any other names than "rsh",
"rshell" or "remsh" work as you described and use the name it was
called with as a hostname.
