Terminal access will not begin until the Backspace key is pressed. The activation character command can be issued from line configuration mode to help secure access to the console (CON) port, auxiliary (AUX) port, and virtual terminal (VTY) ports. This method should not be used in lieu of implementing strong password security, but it can help to dissuade casual intruders looking for easy device access.

The variable for the activation character command is the decimal value for the ASCII character. By default, the value 13 is used for the activation character, which corresponds to the Enter or Return key. The decimal value 8 corresponds to the Backspace key, not the 8 key? the decimal value 56 corresponds to the 8 key.

The exec timeout command is used to configure a terminal line with an idle timeout. If no input is detected on the line within the idle timeout period, the session is disconnected. The syntax of the exec timeout command is exec timeout minutes [seconds].
Therefore, the exec timeout 1 30 command configures the router to automatically disconnect idle sessions after one minute and 30 seconds, which is equal to 90 seconds. If the exec timeout command has not been issued, an idle session will remain established for 10 minutes without input. Issuing the no exec timeout command or the exec timeout 0 0 command causes a session to never time out due to inactivity.
