# This is a sample Bourne shell script to log a user onto a remote system.
# Things to remember:
#	1) Script files should have permissions of 700, to prevent others
#	from gaining access to your passwords to remote systems.
#	2) The return codes for waitfor are: 0=success, 1=timed out, and
#	-1=error.

echo ""
try=0
# loop until done
while true
do
	# wait 5 seconds for the login prompt
	waitfor -5 ogin:
	# test the exit code of the waitfor command
	if [ "$?" -eq 0 ]
	then
		# send my user ID and exit the loop
		echo "egray"
		break
	fi

	# increment the number of attempts
	try=`expr $try + 1`
	# test to see if we should give up
	if [ "$try" -eq 5 ]
	then
		exit 1
	fi

	# send a modem break and loop again
	pcomm_cmd modem_break
	echo ""
