tnsping, oracle and the oracle listener process

Greetings All, I am writing a VB app that interfaces with and Oracle database. One of
the things that I would like to do is to mimic the functionality of the tnsping utility that comes
with the Oracle client. So, my question is this. Does anybody know of where I can get my hands on specs for the protocol used when tnsping talks to the listener? Is there source code for tnsping anywhere? Does anybody know what tnsping asks of listener when tnsping is invoked? I was thinking of using a sniffer program to watch the request made by tnsping and the response that comes back from the listener. Any and all help would be greatly appreciated.
