z/OS® V1R13 Communications Server provides a new operator command, DISPLAY TCPIP,TELNET. This command displays summary information such as the name, version, and state for all of the TN3270E Telnet servers that are or were active.
z/OS V1R13 Communications Server provides a new option, PASSWORDPHRASE, that allows the TN3270E Telnet server to accept either a password phrase or a password on the solicitor screen. When the new option is specified and you enter a new password or password phrase, you are asked to verify the new entry. Without the new option, new password verification is not requested.
The TN3270E server can dynamically adjust input buffer size based on the amount of data that is received. Dynamically adjusting the buffer size improves the performance of TN3270 connections that receive large messages.
