Serial Port Profiles
Advanced Tab Field Descriptions
Configure the following parameters:
Authenticate User Enables/disables login/password authentication for users connecting from the
network.
Default: Disabled
Enable TCP
Keepalive Enables a per-connection TCP keepalive feature. After the configured number
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 determines how long the IOLAN will wait during inactivity
before "testing" the connection. It should be noted that if a network connection
is accidentally dropped, it can take as long as the specified interval before
anyone can reconnect to the serial port.
Default: Disabled
Enable Message of
the Day (MOTD) Enables/disables the display of the message of the day.
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.
Default: 0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
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)
Dial In If the device is remote and will be dialing in via modem or ISDN TA, enable
this parameter.
Default: Disabled
