Andrew I believe Peter Hunkeler is putting us more or less on the right track here in stating that there is no support for the 3270 data stream from the TELNET client function available from TSO. Of course there may be other vendors somehow supplying this function and, taking his post at face value, it seems Dave Gibney not only knows of one but is using one.
Meantime what is all this about "2 SSCPs in the same Domain"? I can vaguely see - because I used to be a teacher and I had to try to imagine how students' ideas could get tangled - that you may imagine that a VTAM application talking to another VTAM application has to be cross-domain. This is not true: two VTAM applications running on the same system and activated by the same VTAM SSCP can happily talk to one another. However, you seem to be talking about a TELNET client on one system talking to a TELNET server on another system which, if both applications were using the VTAM API would be cross-domain. However, the TELNET client function in z/OS does not rely on the VTAM API. Moreover the TELNET connection has nothing to do with VTAM domains. Read that twice since I see this false connection appears more than once in your post. The only involvement of VTAM in your scenario is from the TELNET server, which happens, confusingly IMHO, to be called the TN3270 server but does need to be distinguished from the z/OS UNIX TELNET server, to the accessed SNA application. Isn't it time for "a show and tell", meaning a demonstration from your customer of what he/she is actually doing and a report back to the eager listeners here in the list? It may be this is all confusion over which server is being used. I haven't used the z/OS UNIX TELNET server (otelnetd) but if it can do what I imagine it may be able to do, it may give the impression that the 3270 data stream is being supported. Assuming my memory is good, I could use TELNET from one AIX system to another AIX system and manipulate SMIT with the cursor keys in what someone familiar with using 3270 devices might describe as a "full- screen" environment. What's interesting about the comparison of the two environments is that the SMIT application reacts to those cursor movements in a way that would never happen with 3270 since there can be an immediate reaction to the character entered rather than having to wait for the entry of an AID key such as ENTER.
