Session Timers
There are timers on Utility Port, Telnet, and web control sessions that terminate them if 
there is a lack of activity.  Any action you take during a session automatically resets the 
timer, and it starts all over again.  The timers and their interactions are described below.
3.4.1
Utility Port Session Timer
The Utility Port Session Timer starts upon receipt of a character from the Utility Port.  The 
timer is reset upon receipt of every character.  If no characters are received for 15 
consecutive minutes, the session terminates.
When a Utility Port Session is in progress, Telnet cannot execute any commands to 
TimeVault.  The Utility Port Session must end before full Telnet access is possible.
3.4.2
Telnet Session Timer
The Telnet Session Timer starts upon receipt of a command line from Telnet, via the NET 
Port.  The timer is reset upon receipt of every command line.  If no lines are received for 
15 consecutive minutes, the session terminates.
Terminating a Telnet session drops the connection to the remote host.  You can 
immediately activate a new session by re-connecting and logging in again.
3.4.3
Web Control Session Timer
Once you are logged in to any Control Page, you can send HTTP requests from a web 
browser, via the NET Port.  The Web Control Session Timer starts as soon as it receives 
such a request.  The timer is reset upon receipt of every HTTP request.  If no HTTP 
requests are received for five consecutive minutes, the session terminates.
Terminating a Web Control session causes TimeVault to deny any further requests you 
make for changes.  You can immediately activate a new session by logging in again.
