I have something funky going on with the controlling terminal

[grocery_stocker]

I was trying to write an auto responder on a local BBS. However, when
I have perl send the BBS respond command to the BBS, I get "Input not
a tty". I'm assuming this is because of the BBS text editor that sits
on top of the BBS or what not.

m-net% more post.pl
#!/usr/bin/perl

use strict;
use warnings;

open my $out, '|-', 'bbs'
or die "cannot open pipe to bbs: $!";

print $out "read 18\n";
print $out "respond\n"; #the respond command
close $out
or die "cannot close pipe to bbs: $!";
m-net% ./post.pl

I was thinking that maybe I could somehow redirect something to /dev/
tty. Ideas?
