Port Buffering

Enables/disables port buffering on a remote system. When you enable this 

option, you have the ability to save the buffered data to a file(s) (one file is 
created for each serial port) and/or send it to the Syslog host for viewing on the 

Syslog host’s monitor.
Default: Disabled

The NFS host that the IOLAN will send data to for its 

 

feature. The IOLAN will open a file on the NFS host for each serial port 

configured for 

, and will send serial port data to be 

written to that file(s). 
Default: None

The directory and/or subdirectories where the 

 files 

will be created. For multiple IOLANs using the same NFS host, it is 

recommended that each IOLAN have its own unique directory to house the 
remote port log files. 
Default: 

/device_server/portlogs

Determines if the data sent to the NFS host is sent encrypted or in the clear 

across the LAN. 
NOTE: When NFS encryption is enabled, the Decoder utility software is 

required to be installed on the NFS host for decrypting the data to a readable 
format. The Decoder utility software can be found on the installation CD-ROM 

and on the 

 website.

Default: Disabled

When enabled, buffered data is sent to the syslog host to be viewed on the 
host’s monitor.   Choose the event level that will be associated with the "port 

buffer data"  in the syslog.
Data Options: Emergency, Alert, Critical, Error, Warning, Notice, Info, Debug.
Default Level: Info
Default: Disabled

Enable/disable time stamping of the serial port buffer data.
Default: Disabled

When enabled, key strokes that are sent from the network host to the serial 
device on the IOLAN’s serial port are buffered. 
Default: Disabled
