Say we have a host alpha and a host bravo that is connected to alpha with serial cable. The following entries are required within /etc/inittab of the host alpha (to make the configuration permanent): T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100 Next, re-read the /etc/inittab of host alpha by running: init q From host bravo, connect with: cu -l ttyS0 -e -o -115200
