Serial console set up on Ubuntu 9.10 - the Karmic Koala
« on: April 13, 2010, 01:18:05 AM »
I cannot for the life of me get a serial console working! :madashell: I've tried an Ubuntu forum (with currently 7982 users online) and no replies. I will probably have better luck here. I see that Ubuntu changed things around, /etc/inittab is gone. It looks as if /etc/init/ttyS0.conf has replaced inittab. Here is what I have so far.

# ttyS0 - getty
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

exec /sbin/getty -L 57600 ttyS0 vt102
redrumloa@redrumloa:/dev$ dmesg | grep ttyS
[    0.974946] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    0.975200] 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
redrumloa@redrumloa:/etc/init$ id -Gn |grep dialout
redrumloa adm dialout cdrom plugdev lpadmin admin sambashare
redrumloa@redrumloa:/etc/init$ ps -ef | egrep ttyS0
root      1560     1  0 19:40 ttyS0    00:00:00 /sbin/getty -L 57600 ttyS0 vt102
1000      2545  2411  0 20:13 pts/1    00:00:00 egrep --color=auto ttyS0
redrumloa@redrumloa:/dev$ ls -l ttyS0
crw------- 1 root root 4, 64 2010-04-12 19:40 ttyS0
The only possible problem I see is in permissions and group for /dev/ttyS0. Every time I chmod (to 777) and chgrp (to dialout), it does not help. I am still unable to log into to a serial console and the permissions and group goes back to default above after ever reboot.

Any help would be appreciated.

Someone has to state the obvious and that someone is me!
