This came up once before,,, I think.  I currently do this with a call to
'cu.'  Not the tool of choice for a lot of folks, but hey it works.  I
had it set up to page me whenever someone logged into my box and
whenever the machine was rebooted.  I then set it up to page me every
hour on the quarter hour when I was having problems with my pager and
wanted to verify that it was functioning properly.  It's called from
cron and is very simplistic.  You can get it done with three lines of
code as follows:

cu -l /dev/cua0 "555,555-1234---$CODETOSEND" &
sleep 25
kill $!

Now it's not very elegant, but it works and works well.  The $CODETOSEND
is the digital sequence you send to the pager.  I've found that I must
explicitly kill the cu call as indicated above.  The '---' between the
pager number and the $CODETOSEND basically provides the time for the
pager system to answer the phone.  I had to play with it to get the
right length of the pause.  You may have to tweek it as well.  Good
luck.
