Here are the steps to deactivate the serial terminal:
- Open the following file: /etc/inittab
- It will look something like this:
::sysinit:/etc/init.d/rcS S boot ::shutdown:/etc/init.d/rcS K shutdown ::askconsole:/usr/libexec/login.sh
- To disable the serial terminal, the line with askconsole needs to be commented out, like so:
::sysinit:/etc/init.d/rcS S boot ::shutdown:/etc/init.d/rcS K shutdown #::askconsole:/usr/libexec/login.sh
- Reboot the Omega and the serial terminal will no longer be available. Note that there will still be kernel messages printed, but the terminal will not be available.
