Authenticate User	Enables/disables login/password authentication for users connecting from the
	network.
	Default: Disabled
Enable TCP	Enables a per-connection TCP keepalive feature. After the configured number
Keepalive	of seconds, the connection will send a gratuitous ACK to the network peer,
	thus either ensuring the connection stays active OR causing a dropped
	connection condition to be recognized.
	This parameter needs to be used in conjunction with Monitor Connection
	Status Interval parameter found in the Serial, Advanced, Advanced Settings
	tab. The interval specifies the inactivity period before "testing" the connection.

the Day (MOTD)	Default: Disabled
Enable Data	When enabled, serial data will be buffered if the TCP connection is lost. When
Logging	the TCP connection is re-established, the buffered serial data will be sent to its
	destination (this option is not available when Monitor DSR, Monitor DCD, or
	Multihost is enabled).
	The data buffer is 4K for desktop models and 32K for rack mount models. If
	the data buffer is filled, incoming serial data will overwrite the oldest data.
	Default: Disabled
Idle Timeout	Use this timer to close a connection because of inactivity. When the Idle
	Timeout expires, the IOLAN will end the connection.
	Range: 0-4294967 seconds (about 49 days)
	Default: 0 seconds so the port will never timeout
Session Timeout	Use this timer to forcibly close the session/connection when the Session
	Timeout expires.
	Default: 0 seconds so the port will never timeout
	Range: 0-4294967 seconds (about 49 days)
