You may want to check out echoping in the /usr/ports/net collection.
According to the docs:
"echoping" is a small program to test (approximatively) performances of a
remote host by sending it TCP "echo" (or other protocol) packets.
- uses the protocols echo, discard, chargen or HTTP,
- uses UDP instead of TCP for the protocols which accept it (like echo),
- can repeat the test and display various measures about it,
- can use T/TCP on systems which support it.
Haven't tried it myself.
