No, this is not possible as the other side is not running
erlang. Introducing an application level "ping" also won't work as the
other side doesn't expect anything (and I can't change that side).

Actually, the ACK, on the TCP packet that I sent, would be the
"pong". The ok I get from gen_tcp:send however does not correspond
with an ACK.
