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 specifies the inactivity period before "testing" the connection.
Default: Disabled
Enable Message of
the Day (MOTD)
Enables/disables the display of the message of the day.
Default: Disabled
Enable Data
Logging
When enabled, serial data will be buffered if the TCP connection is lost. When
the TCP connection is re-established, the buffered serial data will be sent to its
destination. If using the Trueport profile, data logging is only supported in Lite
Mode.
The minimum data buffer size for all models is 1 KB. The maximum data
buffer size is 2000 KB for DS1/TS2/STS8D, all other models are 4000 KB. If
the data buffer is filled, incoming serial data will overwrite the oldest data.
Values: 1-2000 KB (DS1/TS1/STS8D) - Default 4 KB
Values: 1-4000 KB (all other models) - Default 256 KB
Default: Disabled
Note: A kill line or a reboot of the IOLAN causes all buffered data to be
lost.
Some profile features are not compatible with the data logging feature. See
Appendix J, Data Logging.
To change the default data logging buffer size see Advanced Serial Settings
Tab .
