SUSE SLES 8.0 configuration: Note: This procedure is based on a default installation of SUSE Linux Enterprise Server (SLES) 8.0. The file names, structures, and commands might be different for other versions of SUSE LINUX. Complete the following steps to configure the general Linux parameters for SOL operation when using the SLES 8.0 operating system. Note: Hardware flow control prevents character loss during communication over a serial connection. You must enable it when using a Linux operating system. 1. Add the following line to the end of the # getty-programs for the normal runlevels section of the /etc/inittab file. This enables hardware flow control and enables users to log in through the SOL console. 7:2345:respawn:/sbin/agetty -h ttyS0 19200 vt102 2. Add the following line after the tty6 line at the bottom of the /etc/securetty file to enable a user to log in as the root user through the SOL console: ttyS1 3.
