I have a HP LaserJet 4MP which used serial connection to connect with Redhat
Linux ver 5.2, I already installed teh printer driver "hp4mp", it works fine
when I print ASCII testing, but it got error message once I try to print
postscript testing.
The "40 ERROR" definitation is :
"The printer encountered an error while transferring data from the computer.
If you are using the serial I/O, you might have caused this error by turning
the computer ON or OFF while the printer was on line; or your printer's baud
rate or parity was not the same as the computer's."
then I tried to change the closing_wait and closing_wait2 into higher
number, it stills doesn't work. THen I tried another which is matching the
baud rate speed on the printer and serial port are the same (57600, 9600,
etc), it also got the error message.
Anyone have any idea?
I would be appreciated if you could help.

Claude,
I have a SoundBlaste pci 128 and have had it running with no problems
using the oss stuff built into the kernel.
I prefer the alsa driver because it uses more of the cards features and
has a better audio quality. You might look into it to see if this takes
care of the problem.

Sorry I wasn't more specific. Well, I am running Mandrake 5.3 with Kernel
(2.0.36), Xfree86 (3.3.3.1)and KDE (1.1 Final), I have a Dell D825HT
Trinitron 15" monitor, a Matrox Millennium II Video card with 4MB RAM with
the 2164w graphics chip, and the TI 3026 external RAMDAC that runs at 220
MHz (I think it is shown as 230.000 in XF86Config). I am using a Microsoft
Intellimouse with Trackball also. I configured the settings to run at 800 X
600 in all modes 8, 16 and 24. I choose the chipset 2164w, the Millennium
II, when I was prompted for what card I had, I choose CUSTOM for my monitor
type, since mine wasn't in the list. I also manually edited "xinit"
manually to set the Horizontal frequency to 31.5 - 70 kHz (these are
manufacturers specs) and the Vertical frequency to 50 - 120 kHz (these are
manufacturers specs), since I could find the correct ones in the set-up. I
also removed the "#" from the file too in front of the amount of RAM that
the card has too (4096). Finally I specified my keyboard as the Microsoft
Natural keyboard in the file too. I wish I could get Linux to print so I
could have a hard copy of this file to send to people, but I need to tackle
one problem at a time. The first time I got KDE to work the screen was huge
and went off the sides, top and bottom of the monitor. Then I re-ran
XConfigurator and now the screen occupies a small area of my monitors total
space. Plus sometimes the window or dialog box extends below the bottom of
the screen and I am unable to click any buttons to make my changes stay.
thanks in advance.

Subject: Half inch HP tape on Power Mac running Linux: reading errors.
Date: Fri, 07 May 1999 13:09:54 GMT
Dear all;
Well I thought it might not work but it nearly does. I'm running MkLinux (in
fact Linux 2.0.33-osfmach3 on a PowerPC 601) and I wish to read half inch
tapes on an old tape drive which we have connected to it. On booting the OS
identifies the drive as an HP 88780 A662 drive and all appears well. It's
accessible as /dev/st0 and it reports a status as:
# mt -f /dev/st0 status
Unknown tape drive type (type code 0)
File number=0, block number=0.
mt_resid: 0, mt_erreg: 0x0
mt_dsreg: 0x3000001, mt_gstat: 0x45810000
General status bits on (45810000):
BOT WR_PROT ONLINE D_6250 IM_REP_EN
..which is not too bad. I can control the tape, rewind it and stuff and all
was looking remarkably good considering I thought it might not work at all.
However, when using dd to read data off the tape it seems to stop after each
record. The third record is read by:
dd if=/dev/nst0 of=brtape3 ibs=80 cbs=80
... and I would expect this to cat all of the data from that record on to the
brtape file right to the end of the tape. However it just reads one record.
So I'm so close to a solution but yet so far! Damn. Had anyone got any
ideas? Is there a web site with any useful tips for this sort of thing.
I think hardware-wise I'm set up ok, I guess I just need something clever in
dd for it to work? Or is there a config file somewhere where I can tell the
OS what exactly the tape drive is I have and how it might work. Something
like the equivalent of /kernel/drv/st.conf on Solaris I guess.
Thanks in advance for any help everyone!

Hello,
We're having trouble here with some es1370 cards in our office.
We have insalled the cards, and are able to get excellent audio
reproduction (playing mp3 files, for instance), but are unable to
record sound.
We have tried using dd and cat from the device, as well as a
number of sample applications we have written to the OSS interface,
and are unable to do anything except occasionally hear a periodic
pulsing sound?

The thing that makes these CPU's so cheap is the quantity of production,
and the fact that the engineering is already done and the CPU is already
present. In my original post, my point was that if adding a sophisticated
cpu and memory to my printer is going to raise the price by around $50, I
would rather drop that same $50 into my main system CPU and memory. That
way it is usefull to me even when I am not printing.
The only difference between Postscript, HPGL, or any other printer protocal
is the driver support, and the bandwidth used. As I said in my original post,
feel free to criticize HP for introducing an undocumented protocal, they
deserve it. I don't know that they should be criticized for introducing a
low level protocal, however. I think it makes good engineering sense in our
current CPU-Cycle rich environment.
I am not particulary concerned about the bandwidth used on my printer cable.
I own and use both a 8 page per minute postscript laser with 4mb of ram and
some sort of internal CPU, and an HP722 deskjet winprinter. For anything but
printing many copies of the exact same image, the deskjet runs rings around
the postscript printer.

Perhaps I did not make myself clear, I apologize. I did not mean to
generalize about anything but printers, and I only speak of those relative
to my particular requirements (which are pretty typical of the home user).
Last time I priced HP printers, the HPGL and postscript models are all
about $75 to $100 more then the winprinters, and give me no measurable
advantage relative to my printing requirements for either my windows or
Linux environment. They are not faster, they do not produce better print,
and they are no more compatible. Bash HP for not documenting
their protocal, but don't bash them for saving me $100 by not giving me
something that I don't want and that does not help me.
I don't believe the argument you are trying to put in my mouth scales to
video devices. If I put a $100 3d video accelerator in my system, my frame
rate for quake goes from about 7 frames per second to about 30 frames per
second. This is a huge, observable, and measurable difference. I will
be happy to pay for it. If they can find a way to give me that performance
without making me pay $100 more for a new card, and make it work with both
Linux and Windows, I will adopt it in a heartbeat, just like I did the
winprinter.

That is a good point, and if the amount of idle bandwidth on your printer
cable is important to you, then spend the extra $100 for your postscript
printer. If you are printing across a LAN, and you are running up against
bandwidth limitations already, then postscript will probably be very
helpfull to you. Again, I apologize if my original post sounded like a
generalized one-size-fits-all truth, I meant only to say that a low level
protocal like used on the HP 700 series printers has it's place.
I do not face any of these problems, and I am happy that low end consumer
printers and high end network printers are available.

My cost argument here for my printer demonstrates exactly the opposite. By
going monolithic, HP got $100 LESS from me, and I got everything I needed
and then some.
Going monolithic may be good or bad, it depends on the problem requirements.
It's an engineering decision, like anything else. I don't want an external
hard drive on my Palm pilot, but on the other hand I avoid Winmodems like
the plague (mainly because of performance and compatibility problems).
SCSI is another good example, it is superior to IDE in just about every
regard. Except that I can set up my system with IDE devices and do
everything I need to do for about half the cost of getting set up with
SCSI.
Anybody want to buy a 4x SCSI CD-Rom? Only $200. How about a postscript
laser printer, I have two. The first is a Qume Scripten, 10 page per minute
postscript with 4mb ram. Cost $4000 back in 1989, I will sell it to you
for half that much. The other is a Mirror 8 page per minute postscript with
4 MB of ram also. That one was about $500 three years ago, I will sell it for
$350. Of course for normal usage, my $199 HP 722 will run rings around both
of them...

Can't turn the PSN on without a processor reset. That will either
reboot the machine or trigger an OS trap (I can't remember which.) No
user-land code will be able to do this on Linux, though if the
get-the-PSN instruction can be trappen on Linux, the OS might
substitute some bogus random number instead... :^)
IOW, the PSN is not (or will not be in the future) an issue on Linux.
This is 'cos Linux does things right - why penalise it for the
iniquitous failings of M$?

From: [EMAIL PROTECTED] (David Morgan)
Date: Fri, 07 May 1999 15:18:06 GMT
Hello!
Has anybody seen or know info about how much performance you would gain if you
used added a second cpu to a script intensive webserver? (e.g
apache+modperl/php+database)
I'm having a hard time trying to decide to just get an abit bh6 rev2 and
whatever I can afford cpu, or if it is worth it to spend the bucks on a dual
cpu board with the affordable idea that I could pop in the second cpu down the
road as needed?
Does linux break the apache's client requests over the two CPU's ? It seems to
me, with the great linux disk cache, the disk won't be limit factor, it will
be, (hard to say in linux world), cpu limited.
Any info, links would be great!
PPS, there is lots of info on single cpu motherboards (and it seems like bh6
rev2 is near the top of the list by many), but I've not seen much on dual cpu
boards. Since UDMA works well for Linux, the ASUS P2B-DS is such an expensive
board (especially if you are not going to use scsi), and I have not heard much
about the reliability of other DUAL cpu boards. Info on this would also be
much appreciated.
Thanks so much!
