Yes, I call stty from the perl code like

system "stty", qw"-echo -echonl -echoke -echoe -isig" and
        die "error during stty";
...
system "stty", "sane" and
        warn "cannot reset stty settings";

in a script I've written. Replace the flags with whatever you want. If you don't want to install addittional modules, I doubt there's a simpler way then these two.
