Would bb.pl be of any use to you??  As found on deadcat.net:

#!/usr/bin/perl -w

# bb.pl
#
# BIG BROTHER CLIENT PROGRAM
# Nicolas Chuche <chuche at teaser.fr>
# Version 1
# Jul 15, 2000

# This program is a remake of bb.c in perl.
# I've do that to :
# 1. have a real client for my NT servers
# 2. see what it done in perl

# I've tried to have full compatibility so i've keep all the error
# messages.

# If you want to use it, just replace the original bb by this file in
# BBHOME/bin

# The header of bb.c :

# SENDS THE INPUT LINE TO THE DAEMON ON THE BIG BROTHER PORT
# Format: bb IP-ADDR [<LINE>|-]
#
#    IP-ADDR:    IP-ADDR OF THE SERVER
#    LINE:        <page|status|summary> <DATA>
#        DATA:    for page:    <NUMERIC MESSAGE><status-msg>
#            for status:    <machine><color-code><status-msg>
#            fro summary:    <summary name><color-code><http link>
#
#    -        Will read from standard input a one line status
#                message.
