This may not be what your looking for either Kent, but... Install the beep package. Then, using bash, write a program to output to the case speaker like this. A="/usr/bin/beep -l 80 -f 1000 ;sleep .1;/usr/bin/beep -d 100 -l 250 -f 1000" B="/usr/bin/beep -d 100 -l 250 -f 1000 ; sleep .1;/usr/bin/beep -l 80 -r 3 -f 1000" etc I have 'UP' sent every 5 minutes if I'm connected to the net (dialup).
