Overview
This page describes different methods for setting up a serial console post booting up an NST system. See Getting Started - Server Boot for setting up a serial console initially during a NST Live boot.
Serial Console On NST 2.13.0
Use the following command to manually enable the serial console on NST versions 2.13.0 using upstart. This example will set the serial baud rate to: "57600" and use serial device: "/dev/ttyS0".
[root@probe ~]# initctl emit --no-wait fedora.serial-console-available ttyS0 57600
[root@probe ~]#
Serial Console On NST 2.15.0 or Above
Use the following command to manually enable the serial console on NST versions 2.15.x or above using systemd. This example will use the current baud rate (agetty -s option) set typically during a boot time and use serial device: "/dev/ttyS0".
[root@probe ~]# systemctl start serial-getty@ttyS0.service
[root@probe ~]#
To get the serial console status use:
[root@probe ~]# systemctl status serial-getty@ttyS0.service
serial-getty@ttyS0.service - Serial Getty on ttyS0
Loaded: loaded (/lib/systemd/system/serial-getty@.service)
