The following describes some miscellaneous variables which control Intercom's behavior. They are straight-forward and don't need a section of their own.
![]() | Typing set with no arguments will display a list of valid variables with a brief description of their function. It may be more up-to-date than this document and consulting it is recommended. |
cmd_maxdepth - Controls the depth of command-recursion permitted before Intercom flags a command-loop and aborts the operation. A command-loop can be as simple as setting up an alias a to b and b back to a or can be much more complicated. The cmd_maxdepth variable exists to protect against such occurrences. The default value is 10 and should be enough for most anyone.
history_limit - This variable controls how many lines to keep in Intercom's command-history if the readline library is used. The default is 100 lines and is usually enough for most people.
reverse_lookup - If set to 1, a reverse DNS lookup is performed on connected hosts whos results are displayed when a call is connected and terminated. If set to 0, this lookup is not done and the IP address is displayed. REverse lookups can take time so if connection times are important, you can disable this; however, the default is enabled ad the results can be informative.
verbose - When set to 1, Intercom becomes a little more verbose in its output to the console.
snd_loopback - When set to 1, audio data which is received is bounced immediately back to the sender. It is quite useful for troubleshooting audio problems. Local audio is not sent to the remote party when this option is used.
