More confusion...I mentioned only one ping, where did you come up with two? lol
1. Your original post.
2. My description of "TPOD" (for some reason, I didn't even pick up on the F7 reference, and I immediately remembered when a student came in to learn our telephony software and started to shut down the instructor's PC as it was streaming audio simply using "ping blah -t", hence my reference and all the aforementioned confusion :)), and
3. The version you looked up.
So, there you have it. All the versions that I described. Make more sense now?
