New Keep alive feature in Rumba version 9.4 and above
When Rumba is connected to a mainframe over a network via TCP/IP, TCP Keepalive feature can be used to determine if the connection is still active. Enable this feature if you want the host connection to be monitored for connection issues. This feature can be enabled by executing the following steps:
Click on Connection > Configure > TN3270Advanced tab. Select “Send KeepAlive” option. Two options are provided for this feature:
Enables TCP/IP connection monitoring. This depends on host generated Keep Alive packets.
Enables Rumba to transmit NOP packets on an idle connection to maintain connectivity and detect connection failures. Use the Interval field to specify the interval, in seconds, at which to send the packet.
