Rephrasing:
TN3270 is merely TCPIP on one side and VTAM/SNA on the other... TN3270 receives TCPIP requests on one side and translates to VTAM/SNA on the other. (BTW, VTAM also supports BISYNC). Other points: Once you have the READY prompt you *ARE* logged on to TSO. TELNET (dnsname or ip addr) invokes a TCPIP connection to the target, thus would require a TELNET or TN3270 server on the target. TN3270 used to be a part of the TCP/IP address space, but was moved (mandatory) to a separate address space circa z/OS 1.9. <snip> >VTAM is the pre-req, not TN3270. > >It depends on the method of *TERMINAL* attachment.

And no one has mentioned that it's possible to log on to TSO (the posed question) at the "READY" prompt with TELNET, but without TN3270. (Or is TN3270 part of the TELNET daemon nowadays?) </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
