Session Profiles → Idle Action

Here you can set an action to be executed when the keyboard has been idle for a number of seconds. A time of zero disables the action.

If you want to prevent a disconnection by the remote site due to inactivity, the action can send a character, or perform another action (e.g., start a script or send a special key of an emulation).

When sending a character, 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 do nothing, choose no action, or set the idle time to zero.
