Since the internet is unreliable some of the time, it is possible to set up your character to depart Avalon should nothing be received from you over a period of two minutes. To turn this facility on, type TIMEOUT ON, and to turn it off, type TIMEOUT OFF. After two minutes of inactivity, Avalon will forcibly execute the equivalent of a QUIT command.
If two minutes is too short, if you find yourself getting disconnected too early, you may activate instead a FIVE minute timeout by using TIMEOUT LONG.
