CHGTELNA TIMMRKTIMO; "Dead client timer" more accurate than KEEP ALIVE

I will see what happens when I change
From: CHGTELNA TIMMRKTIMO(*CALC)
To: CHGTELNA TIMMRKTIMO(60)

I read the CHGTELNA help text and this long IBM document:

http://www-01.ibm.com/support/docview.wss?uid=nas1a53b17cf8d5ed7c386256c

The Session Keep Alive parameter specifies the number of seconds

between session validation.

KEEP ALIVE is a poor term to use for this mechanism because it is
misleading.
This mechanism does not keep a Telnet session alive. It is a probe to

detect when a Telnet session is dead. Dead client timer would be a
better name.
*CALC IS APPROXIMATELY 600 SECONDS OR 10 MINUTES.

The changes take effect the next time the TELNET server is started
either by
the Start TCP/IP (STRTCP) command or by the Start TCP/IP Server
(STRTCPSVR) command.
Note: The CHGTELNA command parameters are used by the TELNET

server only; they are not used by the TELNET client. Many of

these same parameters can be set for TELNET clients using the

Start TCP/IP TELNET (STRTCPTELN) command or the TELNET client

subcommands.
