Session Profiles → Idle Action

Here you can set an action to be executed when no characters have been sent or received for a specific period.

If you want to prevent a disconnection by the remote site due to inactivity, it is possible to automatically send characters or perform another user-defined action in this case (e.g., start a script or send a special key of an emulation).

When sending characters, you should first try to use characters that do not trigger unwanted actions on the remote site, such as the null character (hex 00), Esc, or if necessary, Enter. For Telnet connections, the TELNET_NOP packet can also be used for this purpose.

Alternatively, ZOC can disconnect the connection after inactivity so that, for example, modem connections are automatically limited in duration.

To perform no action on a timeout, the timeout period must be set to zero or you need to set the custom action to 'no action'.
