Don't use tip/cu. You don't need any interactive response, so just
write a program in C, Perl, TCL, shell, lisp, basic, or IBM JCL that
does this:

	Opens /dev/whatever_your_version_of_unix_calls_the_line
	Sends "+++"
	delay 1 second
	Sends "ATH\r"
	delay 1 second
	Sends "AAAAAA"
	delay 1 second
	Sends "ATDT<insert-pbx-junk-here><insert-beeper-number-here>,,,<insert magic codes here>"
	Closes /dev/whatever

This will get the modem's attention no matter what mode it's in, and send
the stuff. Try this:

                        ---------------
#!/bin/sh
Usage='beeper <number> <message-id>'
Tty='/dev/modem'
Pbx='9w'
Commas=',,,'  # Adjust delay for your beeper arrangement.
#
case $# in
  2) ;;
  *) echo Usage: $Usage;;
esac

Beeper=$1

# These are the numeric magic codes we use.
case $2 in
  information) Message='4110000';;
  warning) Message='6110000';;
  fatal) Message='9110000';;
esac

(
stty -echo -nl
echo -n '+++'; sleep 1 # You did say you were using Suns
echo 'ATH'; sleep 1
echo -n 'AAAAAA'; sleep 1
echo "ATDT$Pbx$Beeper$Commas$Message"
) > $Tty
