On ping
From Scriptwiki
The on PING event triggers when a server sends you a PING message to see if you're still connected.
on <level>:PING:<commands>
Read access levels to get more info about the <level> field.
Note that you can't use this to intercept /pings to your own nickname, this is used internally by mIRC.
Example
on *:PING: {
echo -a Got a ping from the server: $1-
}
This example would trigger on every ping and echo it to the active window.
