This works for me:

#!/usr/bin/perl -w

use strict;
use vars qw($ret $reply);

# Signal handler
$SIG{INT} = 'intSub';

while (1) {
    $ret=get_input();
    print "\nget_input returned: $ret\n"; 
}

sub get_input {
    # Give prompt
    print "Enter value: ";
    $reply=<STDIN>;

    return 0 unless $reply;

    chomp($reply);
    print "You typed: $reply\n";

    return 1;
}

sub intSub {
    # Reset signal handler
    $SIG{INT} = 'intSub';
};

I've only used this code on win2k, so I can't say that it will work on *nix boxes. You'll have to try that for yourself.
