I have a problem on the serial port of the server. The console works fine on other servers, we try a onother console to, but all we get are non readable signs on the console.
We do a reset the console into factory default
but the same fault.
The server boot and is accessible over network.
Any idea to set/test the serial console port??
Regards peter

Re: configuration console port D-370
Since your console works elsewhere AND other consoles pluged gives same results, why not do a rmsf /dev/console and a insf -e just after ?
All the best

Re: configuration console port D-370
You talk about testing console elsewhere but are yoiu sure that tty settings at the othe place are same. Default tty settings for a terminal on console of D3XX is 8 Data Bit,1 Stop Bit & No Parity. Just set your terminal settings to these and try. As it usually use to be a terminal settings/Cable problem when junk is displayed on terminal. Also check the getty entry in console as after booting the system the terminal settings depend on this entry but before booting it takes default entry.
Just for verification just try to reboot server remotely if you can.
Serial ports can be tested through mstm/stm.

Re: configuration console port D-370
Try the different baud rates. I will take a while but there is not to many of them. I think your D-Classes console is at a different baud rate.
Call it a hunch

Re: configuration console port D-370
I tried all:
- Reboot
- Set diff. Parameters on the console
- insf -evd cn
- copy /dev/console Parameters with:
stty -g < /dev/console
&
stty d26:1805:1970:2b:0:3:1c:8:15:1~ /dev/console
But still the same.
Is it possible to reset the firmwaresettings
without a console? (from the OS)
Regards Peter

Re: configuration console port D-370
As I said I had a case where the console got corrupted by a cr.Xd script that launched a transactional engine and worked fine in interatcive mode, only the terminal emulation it needed was Tip...
I solved (tried allsorts...) by rmsf /dev/console, switch off the console and reboot while coming up switch on the console and let the system recreate the missing device...
Because when corrupted I noticed that at reboot it displayed correctly until the boot hpux...
Maybe will it work for you?
All the best
Victor

SolutionOnce HP-UX is booted and running, the console settings can be seen (without a working console) with:
stty -a < /dev/console
That will give you the current baud rate on the port. In HP-UX (not the firmware or early selftests and bootup) the baud rate and other stty settings are kept n /etc/gettydefs. The console is kept alive (login capable) with /etc/inittab and the console entry.
