If you check back you were te first, to bring up "IP". sjw Date: Fri, 2 Jul 2010 03:45:26 -0700 (PDT) >And what makes you think that the missile launch computer won't >use IP to talk to the target tracking sensor computers?

So, now you are trying to say you did not talk about "IP". "IP" ("Internet Protocol") is a protocol that is use on network cards or network modems. Now ISDN, is an example of a network where most of its modem is normally connected to the system through an serial interface. In a ISDN system the network uses an "Internet Protocol" but on the serial sise it uses a different communication protocol than "IP". But the ISDN modem or any other network card/modem/Wifi might be weight difference between a getting the job done or giving the technology to the guy you were trying to kill.
