Title: Cant get serial console to work
Post by: derTyp on August 08, 2017, 10:20:13 am

Hi,

I have a problem getting the serial console to work on my setup. I have a ASRock J3455B-ITX connected via a null modem cable to my NAS. The NAS is a Debian 8 Box (some Supermicro atom board).

In System->Administration I did set the primary console to serial with 115200 baud and secondary console to VGA. The VGA console started working after I disabled authentication but the serial console is not working no matter which settings I choose.
I can see the boot process on the serial console (I am using "cu" on the NAS to connect) but after "Mounting filesystem" it stops and doesn't display anything.

I want to get the serial console to work prior to updating to 17.7 for eventual debugging. I appreciate your help.

Can you post the output of these two commands, please?

# tail /etc/ttys
# tail /boot/loader.conf
