It turns out that you have to do a lot of fancy stuff to get "xgrab" to
work because you need some of the X11R? widgets that HP doesn't provide. 
Any, I grabbed "xwd2ps" which converts an XWD into PostScript and *does* 
handle color!  This works fine for windows that don't use 3D graphics
from Starbase.  The "xwd" command returns a blank screen when the graphics
are 3D starbase.

xwd2ps can be found in 'export.lcs.mit.edu' in the 'contrib' directory.
The compressed tar file is pretty small, around 160k I think.

Thanks for all those who helped.

Default gateway support is one of a number of networking enhancements and

I'm trying to compile GNU emacs-18.58, and find that it is calling for the
curses library, which seems to be absent from my HP710. Is the curses
library unbundled in HP-Land (so much else seems to be), or is it called by
another name, or is it included somewhere else, or am I completely hosed?

Suggestions on how to proceed are welcome.

On a related matter: whatever happened to yacc and lex? I note these are

Thanks, but no thanks.  Our mission-critical 980 is going to wait for 4.5.
4.0 beta testers have warned me that it was quite buggy, with a lot of
heavy-duty internal changes.  I plan on living with 3.0 networking limitations

I don't either, but this is standard behaviour -- vi on UNIX doesn't
lock the file until it wants to write on it, so with multiple active edit
sessions, the last writer will win. This problem is partially handled by the
RCS/SCCS source code control systems which require a user to "check out"
a routine before touching it, and if you can't "get" a routine, you better
not try to edit the source file that you will find lying around
somewhere because someone else is working on it.

I don't know if your PC editors will try to lock the file for
the duration of the edit session, but I doubt it (they would have to
be "network-aware" versions, since on a normal PC, DOS won't prevent
this). In any case, it would have to be done by the editor; NFS doesn't
lock anything automatically. [ HP gets 1/2 point :-) ]

There is also the possibility that even if your clients and PCNFS are
trying to do the locking, 'lockd' doesn't work -- the version
originally distributed by Sun certainly didn't do anything, and
I think HP-UX 8.07 came out (or the distribution was frozen, which would
be about 3 months earlier) before the fix did. [ Sun may get 1/2 point
though I bet they didn't tell you why HP's lockd may not work :-) ]

Could be, but if that doesn't fix it, contact HP.  They have acknowledged
problems with the 700 series mouse - they fail.  I believe the program to
correct the situation is called "red stripe".  Your dead mouse needs to be

Subject: installing 8user license over instant ignition
Date: 21 Aug 92 20:29:45 GMT

Help.

We ordered a 720 with 8 user license, and everything apparently 
came in.  When we booted the machine and hung a terminal off of it,
we found out that the version of HPUX we are running is still
restricted to the "customary" 2 users!

Well...3 more tapes came with the system:  HP-UX Install Tape,
HP-UX RUNTIME support, and HP-UX RUNTIME 8-user, so naturally,
we assumed that all we had to do was to load the 8user tape
via update.

The message that pops up during the pre-update stage is:

----------------------------------------------------------------------
WARNING: License fileset 08-USER is selected for loading, but it does not
match the license level of the currently running system, which is 02-USER.
If necessary, unselect the 08-USER and select the appropriate license fileset
under the OS-CORE partition, that is, the fileset for the license level
you desire or purchased.
----------------------------------------------------------------------

Shouldn't the tape have all the info and license stuff we need to 
get the 08-USER fileset from the OS-CORE?  Or is there something
screwy going on here?  Do we need to reinstall the whole thing starting from
the INSTALL?...or re-update 8.07 (which would be pretty brain-damaged!)
from the runtime tape?  If that is the case, then there is no point
of having Instant Ignition if it does not allow you to add the multi-user
fileset.


Thanks in advance.

Please excuse me if this isn't the correct place to post, but I`m at the
end of my rope.

I`m trying to hook up an HP7580 drafting plotter to a Sun SPARC2.  I have tried
a couple of different printcap entries, but none seem to work.  All that happens
is the error light on the plotter going on.  I get no error messages on the
Sun side.

Here are the settings on the plotter:
9600 baud
RS232 cable in the "TERMINAL" port (straight through cable)
RS232 dip switch settings:	Parity OFF/ODD
				Full Duplex
				Hardwire
				Normal

It is connected to the TTYA port of the sun.  I have tried a very vanila
entry, that looks like:
hp7580|hp|local D size HP pen plotter:\
        :lp=/dev/ttya:\
        :mx#:sh:\
        :br=#9600:\

        :st=/usr/spool/hp7580/status:\
        :lf=/usr/spool/hp7580/errorlog:

.. and other more complicated entries, but they all cause the error light to
go on on the plotter.

Can anyone give me a clue as to what is going on?  Could I have a hardware
problem with the plotter?

Unreadable blocks are caused by media errors and are NEVER readable. There
is nothing you can do about it. However if you want to read the 
good blocks and save what is left there is a work around. The data must be
really precious. What you need is a new disc identical to the one that
crashed, and create a file system on that new disc.
You have to write a small 'C' program (Which I can provide you
from the time that I needed it) and read all the blocks that you can still read
and write it and the same position on the new disc. For both the read and
the write disc you have to use the raw device and the discs MUST not be
mounted.  After you have done that you have to fsck the new disc.
Mount the new disc and see what is left.

if (ss_flags & SS_INSYSCALL)
	{  "Values for registers 3 through 18 are invalid."
	   pc = ss_gr2	/* RP */
	}
else       pc = ss_pcoq_head.

If you're in the kernel, you have to grab an address (the return pointer)
back in the user program to matched up with a valid stack unwind descriptor.
Trying to unwind with a kernel value of pc and the stack unwind info for
a user program will quickly get you nowhere.
