[erlang-questions] group leader blues

I have two nodes foo and bar on the same host ws1234.
From foo I want to output text in bar's shell.
I tried this
> P = rpc:call(, erlang, whereis, [user]).
> io:format(P, "\nhello\n", ).
Now if the shell in bar looked like this *before* the above command
Then I expected that I should see this:
But instead I see this:
Thus io:format does not work the same way that it does from a process
spawned locally in the shell running on node bar.
So when output from a remote node interrupts input in the local shell
the command line is not erased and rewritten correctly.
I tried various ways of getting hold of the group leader for shell on
the node bar, but non of these seem to work.
Does anybody know what's going on here?
