no display on console

T G Manikandan — Mon, 02 Sep 2002 04:59:43 GMT

I have a 70096 console connected to C3600 machine.

I cannot get the display on the console.

I used this console for my sun machine now probably not working with hp.

can someone help me?

Thanks

Hello,

Since that is a workstation, you actually need a monitor to have full capabilities for CDE. However, you can connect your console to the COM1 port of your C3600 to get a normal text-only access.

Do not forget to run your C-Class in run-level 3, not 4. Vi /etc/inittab.

HTH,
Vince

Hi,

Once other item.

You may need to reset the terminal back to the default settings to get it to work. From memory hold down the 'd' key (could be control-D) when powering off/on.

Micheal,
I did that but still could not get messages on the console.

I have this problem with one or two machines.

Is there something I should do on the display setting on the machine.

Thanks

Hi

There is no terminal configured by default in HP-UX, you need to create one using SAM (or manual). Check the file /etc/inittab for a line like:
a0:3:respawn:/usr/sbin/getty -h tty1p0 9600

sounds as if you have the 70096 connected to SERIAL1 and it is working but not getting any console messages on it but they're displayed on the Graphics? Is this accurate?

You won't get boot messages to the Serial Console unless you change the console path from graphics to the serial path. By adding the inittab entry, you'll be able to login... but won't see console messages.

If you shutdown the box, disconnect the system's keyboard and mouse, the system will default to serial1 when booted up.

To verify/change the console path, interrupt the boot. type "HElp PAth CONsole" for info.

Hope this helps,

It is not that I am not getting any bootup messages,it is that I am unable to see anything on the console,no display.

This is my inittab file

Hi
Is your terminal direct connected to the serial port or via modem. It seems the inittab entry "a0" is a modem connection.

Try removing the USB keyboard and mouse from the system if attached. This would force the output to the rs232 on the older workstations.

Also watch the LCD panel on the system. After POST it should tell you where the console is set to, If it says Console: graphics then it is trying to use the video card. If it says Console: serial or rs232 then it is outputting the display to the serial port.

I did configure a modem on the same machine before some time,that is the entry for that.Now there is no modem.

I could see a grphical card for the system using

#ioscan -funC graphics.

I think probably the normal monitors support support displaying but why dont 70096 monitor models run.

Is that I need to explicitly point whether it is a graphical console or a normal ascii console.

Thanks

Hi
If I remember correct 70096 is a serial terminal. The only terminal entry I can find in your inittab file is the "a0" modem entry (the ttypX is outcommented). I think you should outcomment (or delete) the "a0" entry too and use SAM/Periphal devices/Terminals and Modem/Add Terminal to add a terminal to your system. Without this a serial terminal don't work.
