TCP Client Keep Alive
When in client mode and enabled, TCP Keep Alive packets will be sent from the client to the server periodically in
order to detect a broken connection. The modem will automatically try to re-establish the connection if necessary.
Changing this setting will affect the use of TCP Keep Alive on the next client session. It will not affect an existing
session. When this option is enabled, the timing and number of Keep Alive attempts is controlled by parameters
defined on the External Serial page. It is not possible to have different timing settings for each serial port.
•
PAD Log
If enabled, a log of the data passed through the modem is saved at /tmp/intpadlog. The log will stop saving data
when full and data is lost at modem reset.
