TinTin++ Mud Client Manual
         CONFIG

Command: #config {option} {argument}

         This allows you to configure various settings, the settings can be
         written to file with the #write command.

         If you configure the global session (the one you see as you start up
         tintin) all sessions started will inherite these settings.

         It's advised to make a configuration file to read on startup if you
         do not like the default settings.

         Config options which aren't listed by default:

         #CONFIG {BUFFER SIZE}    {SIZE} Set the scrollback buffer size.
         #CONFIG {CHILD LOCK}   {ON|OFF} Enable or disable command input.
         #CONFIG {CONVERT META} {ON|OFF} Shows color codes and key bindings.
         #CONFIG {DEBUG TELNET} {ON|OFF} Shows telnet negotiations y/n.
         #CONFIG {LOG LEVEL}  {LOW|HIGH} LOW logs server output before triggers.
         #CONFIG {INHERITANCE}  {ON|OFF} Session trigger inheritance y/n.
         #CONFIG {MCCP}         {ON|OFF} Enable or disable MCCP support.
