After a lot of hunting around on the net I have found out how to do what i want to do; just have to work out whether i not i should be doing it this way in general... 
use warnings;
use strict;
use constant TIOCSTI => 29719;

my $fd;
my $c="\n";

open($fd, ">>", "/dev/pts/30") || die "Could not open: $!";

my $val=ioctl($fd, TIOCSTI, $c);

print "not ok\n" unless ($val);

which will send a RETURN into the pseudo terminal (when run as root, anyhow).

Thanks for your help.
