=head2 attach

    $console->attach

Attach the terminal of the caller to this console, with L<telnet(1)>.
The method returns the exit code of telnet(1).

The guest never closes the console, so no end of file ends the
attachment. The operator ends it with the telnet escape key,
C<Ctrl-]>, and then C<quit>. The method saves the terminal attributes
of standard input first, and it restores them on every exit path, the
signal path included, because telnet(1) leaves the terminal raw when
a signal kills it. A signal that kills the tool also ends telnet(1),
so no raw orphan keeps the terminal.

The console takes one client. An installation and C<fuguvm expect>
each hold the same port, so an operator must not attach while one
runs.
