I have a service defined as so:

define service {
 use                             generic-service
 host_name                       db
 service_description             AppServer
 is_volatile                     0
 check_period                    24x7
 max_check_attempts              4
 normal_check_interval           5
 retry_check_interval            1
 contact_groups                  admins
 notification_interval           60
 notification_period             24x7
 check_command                   check_tcp!db.foo.com!3737!PING\n!ACK
}

But that doesn't work even when using the command line like so:

$ /usr/lib/nagios/plugins/check_tcp -H db.foo.com -p 3737 -s 'PING\n' -e 'ACK'

What does work is putting actuall newlines but you can't do that in the config
file. I remember reading about a character sequence you're supposed to use for
newlines in the config files but I can't find it anywhere.
