HP-UX 11v1: Unable to access system via serial terminal
After inserting the line
ttp0:234:respawn:/usr/sbin/getty -h tty0p0 H
in /etc/inittab and re-initializing with init q I did not get a login prompt on an attached terminal.
# ps -ef | grep -e 'getty'

root 13642 13602 1 20:53:54 pts/8 0:00 grep getty
When I start
# /usr/sbin/getty -h tty0p0 H
interactively, I get access as expected. Also I did not have any problems with the procedure described above on a 11v3 machine,
# ps -ef | grep -e 'getty'
replies
Ideas, hints, solutions are very welcome—thank you in advance!

Re: HP-UX 11v1: Unable to access system via serial terminal
Strange behavior: If I change the inittab-line to
ttp9:234:respawn:/usr/sbin/getty -h tty0p0 H
and do an init q the getty-process gets started and a login is possible.
After disable getty on tty0p0 and reset it to
ttp0:234:respawn:/usr/sbin/getty -h tty0p0 H
everything works as it should! A
# ps -ef | grep getty
shows
root 4510 1 0 Jul 24 console 0:00 /usr/sbin/getty console console
root 21254 21233 0 11:12:48 pts/8 0:00 grep getty
root 20493 1 0 10:55:30 tty0p0 0:00 /usr/sbin/getty -h tty0p0 H
Was there something like a ‘lock’ on ttp0? Any explanations are appreciated.
Greetings from a greenhorn!
