Ok I think I go itt.  My mistake was misinterpreting your instructions.  I thought "line console" took care of telnet also.  I see now that I need to use "line telnet" separately.  Knowing about "show line" helped me understand. Thanks again.  If the timeout behavior changes today I will mark the problem as solved. 
Default, apparently 5 min, is too short for me.  I have tried several CLI commands I found online but apparently not the right one.  This in particular seems like it should work but I get an unrecognized command response. console(config)# ip http timeout-policy 1200  
How do you reset the user inactivity timeout for the GUI login on a 3524P?
