Enable Serial Console on OmniOS

README

Just for reference, how I enabled login on SoL for me.
 
As this ticket pops up as first hit for me when searching for OmniOS serial console.

bash

# add definitions for com0 and com1 (change 115200 if using different speed)
sttydefs -a com0 -i '115200 hupcl opost onlcr ofill' -f '115200'
sttydefs -a com1 -i '115200 hupcl opost onlcr ofill' -f '115200'

# only do this if you want root login on serial ports
sed -i 's/^CONSOLE=/#CONSOLE=/' /etc/default/login

# export the current service, patch it and import it (see patch below)
svccfg export console-login > console-login.xml
patch < console-login.patch
svccfg import console-login.xml && rm console-login.xml console-login.patch

# enable com1 (my SoL port, using supermicro board)
svcadm enable vtdaemon:default console-login:com1
