Peter > telnet daemon / inet daemon listening port (623 or 1023 are widely used)
... although they don't have to be since VIPAs and the PORT list BIND parameter are there to allow use of port 23 for access using the z/OS UNIX TELNET server to z/OS UNIX as well as using port 23 to access the TN3270 server. Then, with the aid of your preferred name to IP address translation, you can access either TELNET server by name. What's this "over 3270"? Where did that idea come from? And what's "raw mode"?[1] Perhaps there's some reflection here of the thorough confusion IBM has created - as they do again and again - by calling the original z/OS TELNET function the TN3270 server when it also quite happily - and with not a whiff of 3270 in sight - supports the "network terminal" protocol - otherwise known as "line mode" or LINEMODE. A cleverer and more technically accurate name would be the TELNET SNA gateway server. This would distinguish it from the z/OS UNIX TELNET server which abjures SNA! How would you describe a 'full-mode' tn3270 client? Perhaps a client which completely emulates being a TN3270 client with support for minimally 3277 level of 3270 data stream support? [1] The only "raw" I know in the Communications Server IP component is in the terminology used to differentiate using TCP or UDP from some other "transport" protocol such as ICMP.
