5.2.5.1 “?” 
 
The “?” is a special help character in the EM316LNXNM-OT command line. In previous 
releases, the “?” character did not echo to the display when typed. Beginning in version 4.0, 
the “?” displays as other commands do. Results of the help request are displayed 
immediately to the monitor. 
 
The box below shows the output of the “?” typed alone on the command line in the slot-level 
configuration context. In other contexts, the display is different to reflect the commands 
available from the current prompt. Navigate to each operational context and type “?” at the 
prompt to become familiar with these commands in your environment. Also notice the 
different help output in the slot-level context of a different Fiber Driver module type. The box 
displayed below is specific to EDFA modules. The same command list displays for slot 1.4, 
except that the “reset” (highlighted) command is not available. 
 

 

 
 
The “?” may also be used in two ways after a command typed at the prompt in any context. 
When typed immediately after a command line entry with no space separating it from the 
command, the “?” displays a list of commands that match the preceding string and a 
description of each matching command function. When a space separates the command 
string from the “?”, the display shows the first matching command and a list of the options for 
the next required parameter on the command line. 
 
Read more about the “?” help character in the EM316LNXNM-OT User Guide. There is no 
substitution for practicing the command to become familiar with its behavior.
