It is true that TCP/IP uses a pair of unidirectional channels. This requires that when the ends of the connection are "plugged in", that the talking channel on System A is connected to the listening channel on System B. And that is controlled by the adapter number on the LINK statement. One size is 0, the other is 1. From your previous post, that looks fine. The only other thing I can offer is to ensure that the MTU size is the same on both sides. Alan Altmark z/VM Development IBM Endicott
