Boot to ISL and use the conspath
command to change the console back to rs232.  The command to use is:

serial
        conspath 2/0/4.643
graphics
        conspath 1/0/0.0

This contradicts the PA-RISC Booting HOWTO:

-----

3.1.2.3.3. How can I change the boot console to serial on a 712?

Unfortunately, you can't. Although 712s are configured for in-house HP
development to use serial console, this configuration isn't supported
in the field. You have to use a graphics console for 712s.

-----

I'd like to know if this needs to be corrected.

The above statement about serial console not being "supported" on 712 is 
correct. That doesn't mean you can't do it. Here are the instructions,

-------------
CONFIGURING A RS-232 CONSOLE on a 712

An RS-232 console is not a supported feature in the 712 products. For this 
reason users cannot select the RS-232 port as a console from the BOOT_ADMIN 
prompt.

These instructions will configure an RS-232 console with 9600 Baud, 8 data 
bits, 1 stop bit, and no parity.

HOW-TO INSTRUCTIONS

NOTE: If the following instructions are not entered correctly, your system 
may be left in an un-usable state. Contact support to "dagger" your system 
in this case.

     Power up the 712 system. 
     Press (ESCAPE) during boot to abort auto booting the system. 
     At the BOOT_ADMIN> prompt, use the boot command and the isl keyword.
        This will stop the boot sequence at ISL instead of booting to the 
OS.
     For example: 'boot scsi.6 isl' 
     At the ISL> prompt, type 'conspath 2/0/4.0x283' 
     At the ISL> prompt, type 'disp' and verify console path is:
        (hex) 2/0/4.283.0.0.0.0.0 
     If necessary re-type the conspath command above. 
     Connect an RS-232 terminal to the system. 
     Power cycle the system to bring it up on an RS-232 console. 
-------------

As it indicates above, *BE VERY CAREFUL* or you can hose your system. If 
you
do, I have one of the "dagger" cards that can be loaned out to fix it.

Is there a way to use a serial console with a 715 however?

As someone mentioned previously, just unplug the keyboard. Almost all HP-PA 
workstations will go to serial if they can't find a keyboard. The only one 
I know of that doesn't is the 712. If you want to force an HP-PA 
workstation to serial(even if a keyboard is plugged in) then set the 
console path in the firmware. It varies by machine but it's usually pretty 
easy. The "help" command should give you an example for the machine you're 
on. The 712 was purposely obfuscated so people wouldn't use serial console.

Yes, and it features in the HOWTO:

http://www.oswg.org/oswg-nightly/oswg/en_US.ISO_8859-1/articles/parisc-linux/parisc-linux-boot/preparation.html#SERIALCONSOLE

i've used a 715 in this configuration myself.

Another method:
PDC will use serial port 1 as console if one holds TOC button (near
the power button) for about 10 seconds while powering on.

I seem to have managed to set my console on my 712 to be neither serial
or graphics.  When HPUX boots it seems to detect the console is serial
and I get a login prompt and console messages on my serial terminal, but
it is not really the console as I see no messages from ISL etc on the
serial port.
I think I incorrectly typed the console path when I changed it :( .

The machine boots fine and I can telnet to it etc, but I have no way of
accessing the PDC/ISL.  Before I managed to do this I upgraded it to the
lastest firmware.

Is there some HPUX (10.20) command or trick to alter PDC? ISL?
information to reset my console to a sane state?

I have tried unplugging the keyboard/disks/LAN pretty much everything
really to try to reset it to some factory default.

Thanks.
