How To Guide How to configure the distribution Control-C on default console

Control-C on default console

CTRL-C may not work when using a serial console. This is because, by default, the console is started using the device /dev/console, and any attempt to set the process group of this device will always fail. The easiest way to overcome this is to edit the file/etc/inittab:

host# cd /export/rootfs/<user> 
host# vi ./etc/inittab

Find the definition containing /sbin/getty console and comment it out (with an initial #). Then find the definitions containing /sbin/getty -L. If one of these includes the physical name of the console, for example ttyFW0, remove the comment character (#) from the beginning of the line and check that the baud rate and terminal type are correct. If not, add an appropriate line, for example:

FW0:2345:respawn:/sbin/getty ttyFW0

Note: The physical name of the console is the name passed to the kernel with the console= parameter.
