TN3270E

Telnet is a terminal emulation protocol. With Telnet, users can log on to remote host applications as though they were directly attached to that host. Telnet protocol requires that the user have a Telnet client that emulates a type of terminal that the host application can understand. The client connects to a Telnet server, which communicates with the host application. The Telnet server acts as an interface between the client and host application.

The TN3270E Telnet server (Telnet) provides access to z/OS VTAM SNA applications on the MVS host using Telnet TN3270E, TN3270, or linemode protocol. Telnet acts as an interface between IP and SNA networks. End users in an IP network connect to Telnet, which is also a VTAM application.

For z/OS 2.4 and later, automatically collect data from SMF Type 1154 Subtype 3 to check whether TELNETPARMS statements for all TN3270E servers are configured with appropriate inactivity timeouts, check whether PARMSGROUP statements for all TN3270E servers specify appropriate inactivity timeout values, and more.
