An NOP only requires a TCP ACK response while a DO TIMING-MARK requires a WILL
or WON’T Telnet response. If the server were to send Keep Alive commands, a timeout by
the client would end the session (see Session Termination). Keep Alive is typically used in an
environment where LUs are pooled for use by many users. The purpose of the Keep Alive is
to detect users that have terminated the connection without actually requesting a disconnect
(such as powering down their PC). Once there is no-response detected, LINCS will disconnect
the session and make the resource available to others.
Keep Alive Method applies when LINCS is a TN3270 Server to LAN attached devices, but is
ignored when LINCS is acting as a TN3270 Client for directly attached devices.
KeepAlive Method toggles to NOP (default) or DO TIMING-MARK.
Keep Alive Timer
KeepAlive Timer is the interval in minutes between Keep Alive tests. The range is 1 to 99,
and the default is 5.
Disconnect on UNBIND
This option, when enabled, will cause the TN3270 client to be disconnected whenever an
UNBIND is received for their session. This is typically used for pooled sessions, where it is
important to release the session resource back to the pool to make it available for others to
use. The UNBIND may occur if the user logs off from the application or if the application
times the user out for inactivity.
Telnet Disconnect on UNBIND
This option, when enabled, will cause a Telnet client to be disconnected whenever an UNBIND
is received for their session. This is typically used for pooled sessions, where it is important to
release the session resource back to the pool to make it available for others to use. The UNBIND
may occur if the user logs off from the application or if the application times the user out for
inactivity.
SMS Server
The SMS Server field toggles to enable the SMS Server, and select which line will provide
SMS service. Available lines are LAN lines which have TCP/IP enabled.
SMS Poll Rate
The SMS poll rate determines how fast the servers will be polled for the session and connection
availability data. The poll rate is 5 to 65535 seconds.
SMS Domain Name
The SMS domain name defines the top level domain name node, in the zone of authority of
the SMS domain name server. The domain name may be 64 characters in length.
