Stopping the Ping Command on a Console

Problem: When attached to the serial console of a target, entering Ctrl-C does not stop the ping command.

Cause: If you run the console on /dev/console, BusyBox disables job control, which includes commands such as Ctrl-C and Ctrl-Z.


Edit the file /etc/inittab to use the /dev/ttyS0 device, or whichever device is appropriate, instead of using /dev/console.

For example:

# edit inittab to start of ttyS0 instead of 
# console, and remove vc entries

sed -i 's/console/ttyS0/' ./etc/inittab 
sed -i 's/^.*vc.*$/#\0/' ./etc/inittab
