Or, with no ports needed:

$ ping -n -t 5 -i 10 192.168.200.255

Granted you need to know the broadcast address.  If you know the
interface name, you can get the broadcast address from ifconfig:

$ ping -n -t 5 -i 10 ` ifconfig xl0 | sed -n -e 's/^.* broadcast //p' `

BTW both ping and ifconfig are in /sbin, which is perhaps somewhat
less likely to be in PATH than /bin and /usr/bin.
