Server Commands
prompt-with-name
Displays the Server Name field value instead of default product name. When enabled, the Server Name is displayed in the IOLAN login prompt, CLI prompt, WebManager login screen, and the heading of the Menu. The default value is Off.
single-telnet
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;
zNo active connection to serial port exists and at least 1 second has passed since last connection was terminated.
zAll 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The IOLAN has logic to automatically detect when a reverse connection is no longer active.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 listening for an incoming connection 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 Off.
retry
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.
timeout
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 3 seconds.
