How To Alignment Script that "reads back" RSSI with Beeps..

#
# Mikrotik RB411/433 "RSSI Readback" alignment script
# 
# Based off script by Mark Shumate Feb 2009
# Modified by Randy Cosby June 2009
#
# NOTE: This script may work on other platforms, I
# don't have anything but RB411/433 here in front of
# me. The Beeps will probably work on practically any
# wireless CPE type Routerboard, but maybe the script
# would have to be edited?

# default delaytime
:local lnsdelaytime 230ms;

# name of wireless interface to monitor (default wlan1)

# base freq (as in pitch) of tens digit beep 
:local tensbeepfreq 1200;
#  base freq (as in pitch) of ones digit beep 
:local onesbeepfreq 1100;



# The (veery approximate, heh) running time of the script
# is set here. I am too lazy right now to do this a
# better way...besides, who cares if the thing Beeps 
#  a couple extra minutes right?!? :)

# Here, we set how long the script will beep. NOTE that
# startup/shutdown tones will still be played.
