System: 9000/3XX
O/S: 7.0
According to the HP documentation, the "-C" option to xterm and hpterm
should grab output to /dev/console, but the option does not appear to
work, even if I start the window as root. What do I need to do to make
this work?

The following lines in my .x11start bring up a console xterm --- mwm & sleep 5 # Allow time for initializing hpwm before starting other clients. if [ -z "$COPYRIGHT_SEEN" ] then /usr/bin/X11/xterm -C -ls -geometry 80x24+0+145 -fn iso1.16b -T CONSOLE -n CONSOLE $@ & fi ------ However, in order that your display act as console, you must also have a /usr/lib/X11/Xconsoles file (albeit empty), if my memory is correct (I set up the system about 8 months ago).

I had xterm -C working under HP-UX X11R3 (from HP) just fine on my HP9k375 HP-UX 7.03. I then loaded X11R4 binaries from me10.lbl.gov (work has been a wonderful service !) and this option no longer works. I looked at the code in the source file and it seems to be choking on an ioctl(tty, TIOCCONS, (char *)&on) call in main.c. This is as far as I've gotten. --------------------------------------------------------------------------- Mike Stokes mds@judd.rit.edu (716)-475-7189 Munsell Color Science Laboratory (where color WYSIWYG is becoming a reality) Rochester Institute of Technology Rochester, NY 14623

I prefer to use xconsole from expo.lcs.mit.edu and the r4 distribution.

The 7.0 xterm should work with the R4 server. You might check the permission of /usr/bin/X11/xterm. It should be: ---s--x--x 1 root bin 531932 Aug 4 1990 /usr/bin/X11/xterm Also, the /usr/lib/X11/Xconsoles file should contain a list of the seats (displays) which are allowed to grab console output. If yours is a single head system, a single entry of * will work just fine. Be sure Xconsoles is readable. If none of this works, I can send you the R4 xterm (but it really should work)! -jem -- JEMilburn@lbl.gov ...!ucbvax!lbl.gov!JEMilburn "I don't sing, I don't dance, and I don't like people who do." -Leterman

Do you have a file /usr/lib/X11/Xconsoles with the entry
* ?
That may be the cause of your problem.

What do I need to do to make > this work? The man page for xterm says: -C This option indicates that this window should be receive console output. This is not supported on all systems. ^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^ Also look under XCONSOLES near the end of the hpterm man page for additional details on the -C option.

I've seen various people with questions about having xterm, hpterm take
over the system console. I urge people to take a look at xconsole from the
MIT contrib directory. I like it alot better because because it just presents
console output in an list widget that you can scroll through. It normally is
unmapped but maps itself when it receives output on the console. You can't
miss it because it doesn't look like other applications. I found that using
xterm/hpterm sometimes I didn't notice a message that was sent to the console.
I wrote a simple lp interface for postscript printer, that read messages back
from the printer. These messages were sent to /dev/console, and as a result
the things like "Paper Out", etc. popped up the display. This allowed the
paper to be replaced immediately instead of when someone happened to go to
the printer to pick something up.
I do remember having to do a little bit of work to get it running on HP-UX.
And of course it uses Athena widgets. As always, I switched jobs so I don't
have ready access to the changes I made but maybe I can get someone to
mail me the source code and perhaps a series 300 binary.
