Server Commands

The network subnet mask. For example, 255.255.0.0.

When set, and a custom language file is in use, the login prompt will use the string 

defined in the language file as the login prompt instead of the default prompt, 

.

The number of attempts a user is allowed to enter a password for a serial port 

connection from the network, before the connection is terminated and the user has to 
attempt to login again. For users logging into the serial port, if this limit is exceeded, 

the serial port is disabled for 5 minutes. A user with Admin level rights can restart the 

serial port, bypassing the timeout, by issuing a kill on the disabled serial port.  The 
default value is 

.

Displays the 

 field value instead of default product name. When enabled, 

the 

 is displayed in the IOLAN login prompt, CLI prompt, WebManager 

login screen, and the heading of the Menu. The default value is 

.

In this mode of operation, the IOLAN will only allow for a single TCP connection at a 

time to exist for each serial port configured for a reverse connection type.  Subsequent 

connection attempts will be refused until all of the following conditions are met;

z

No active connection to serial port exists and at least 1 second has passed since last 

connection was terminated.

z

All data from previous connection on the serial port has been transmitted.

The IOLAN has logic to automatically detect when a reverse connection is no longer 

active.  When this happens, the connection is reset and the server can go back to a 

 state.

Applications using Single Telnet need to be aware that there can be some considerable 

delay between a network disconnection and the port being available for the next 

connection attempt; this is to allow any data sent on prior connections to be transmitted 
out of the serial port. Application network retry logic needs to accommodate this 

feature. The default value is 

.

The number of times the IOLAN will attempt to transfer (using TFTP) a file to/from a 

host. Enter a value between 0 and 5. The default is 5. A value of 0 (zero) means that the 
IOLAN will not attempt a retry should TFTP fail.

The time, in seconds, that the IOLAN will wait for a successful transmit or receipt of 

TFTP packets before retrying a TFTP transfer. Enter a value between 3 and 10. The 

default is 

 seconds.

The minimum data buffer size for all models is 1 KB. The maximum data buffer size is 
2000 KB for DS1/TS1/STS8D, all other models the maximum size is 4000 KB.  If the 

data buffer is filled, incoming serial data will overwrite the oldest data.
Data logging is only valid for Trueport and TCP Sockets profiles.
Values: 1-2000 KB (DS1/TS1/STS8D)
Values: 1-4000 KB (all other models)
Default Buffer Size: 4 KB (DS1/TS1/STS8D)
Default Buffer Size: 256 KB (all other models)
